Dear Colleagues,

You are welcome to the following seminar:

**UCC****
Mathematics Seminar**

**Time and location:
**4-5pm, Tuesday 8 October 201=
9, WGB G17

**Speaker: ** Myrto Man=
olaki (University
College Dublin)

**Title:
**An introd=
uction to optimal polynomial approximants

&n= bsp;

**Abstract:**

The notion of
*optimal polynomial approximants* arises naturally from classical prob=
lems in function theory. Such polynomials approximate, in some optimal=
sense, reciprocals of functions in certain spaces on the unit disc, includ=
ing the Hardy, Bergman and Dirichlet
spaces. This talk will give an overview of the subject, with main foc=
us the limiting behaviour on subsets of the unit circle.

Best regards,

Spyros Dendrinos<= /p>

(Joint work with Prof. Andrew Parnell).

This talk presents some current research on statistical anomaly detec=
tion in streaming manufacturing data as part of I-Form, the SFI Rese=
arch Centre for Advanced Manufacturing. Research goals include (i) de=
cision support for machine operators,
(ii) defect detection in build parts and (iii) predicting machine health. =
With the advent of modern dynamometers, IoT sensors, microscopy, and ethern=
et-connected machine tools, we are now in a position to leverage new artifi=
cial intelligence techniques to
quantify the performance and behaviour of the manufacturing process. =
I will also present a novel recursive extreme studentised deviate algorith=
m (R-ESD) to detect anomalies in streaming time series data via statistical=
learning. We adapt the generalised
ESD test (Rosner, 1983) to streaming time series data by using time series=
decomposition and a sliding window approach. This is made computationally =
feasible by recursive updates of the ESD test statistic (Grubbs, 1950).&nbs=
p; Our method is statistically principled
and it outperforms the AnomalyDetection software package, recently release=
d by Twitter Inc. (Twitter) and used by multiple teams at Twitter as their =
state of the art on a daily basis (Vallis, Hochenbaum and Kejariwal, =
2014).

We mark the start of our 4th year of monthly Maths Ireland=
blogs with a piece on Marsh's Library in Dublin and some of the mathsy=
material there

Back in January 2017 we did a similar=C2=A0piece on the Wor=
th Library=C2=A0

MACSI at the department of Mathematics and Statistics at the University of =
Limerick invites you to a seminar
Date: Friday 11th October 2019, Room A2-002 3p.m.
Speaker: Prof. Antony Unwin (Institut f=FCr Mathematik, Universit=E4t Augsb=
urg, Germany)
Title: Understanding Potential Outliers using the O3 Plot.
Abstract: Outliers may be important, in error, or irrelevant, but they ar=
e tricky to identify and deal with. Whether a case is identified as an out=
lier depends on the other cases in the dataset, on the variables available,=
and on the criteria used. A case can stand out as unusual on one or two v=
ariables, while appearing middling on the others. If a case is identified =
as an outlier, it is useful to find out why. This talk discusses the O3 plo=
t (Overview Of Outliers) for supporting outlier analyses. O3 plots show wh=
ich cases are often identified as outliers, which are identified in single =
dimensions, and which are only identified in higher dimensions. They highl=
ight which variables and combinations of variables may be affected by possi=
ble outliers. Applications include a demographic dataset for the Bundestag=
constituencies in Germany and a university ranking dataset.

Dear colleagues,
We will have Mathematical Finance seminar on Friday (11th October).
Everybody welcome,
Ryan
title:: DCU Math Finance (Sergey Nadtochiy, IIT)
content:: Title of talk: Receding front propagation systems: from Finance
to Neuroscience, to Physics
:: I will present the recent advances in the study of particle systems that
are used to
:: model time evolution of a frontier separating two domains.
:: The distinctive feature of such models is that the frontier moves toward
(as opposed to away from) the particles that hit it.
:: This feature appears naturally in the mathematical models for credit and
computer networks, neuron cells, supercooled liquids, etc.,
:: and it constitutes the main challenge in the analysis of such systems.
:: First, I will present several general results on such systems, including
their well-posedness and
:: a characterization of the singularities of the frontier.
:: Then, I will use one of such systems to define and analyze a credit
network game, where
:: the edges of the network represent credit exposures and are determined
dynamically by the nodes themselves.
:: Remarkably, this game admits a very explicit equilibrium in which the
future interest rates and credit exposures
:: can be easily computed for all (risk-neutral) market participants, given
:: the expected returns on their external investments, the constraints on
their credit exposures, and the initial distances-to-default.
:: (Based on joint works with F. Delarue and M. Shkolnikov.)

Mathematical Modelling of the Bovine Reproductive Cycle
The Ideal Candidate:
Since the project is mathematical modelling based on data from a biological=
system, the ideal candidate will have a good honours degree in mathematics=
, computing, engineering or science/medicine. Mathematical candidates shoul=
d have an interest in biology and biological candidates should have an inte=
rest in mathematical modelling. The project can be altered somewhat to suit=
the skills of the successful candidate. Computing skills are an advantage.=
Since the successful candidate will be working and publishing as part of a=
n interdisciplinary team, motivation, communication and presentation skills=
are important.
The Research Team:
This research project involves a collaboration between Dr Leo Creedon and D=
r Marion McAfee of the Mathematical Modelling Research Group (MMRG) at IT S=
ligo, Ireland; Dr Edna Curley, Mountbellew Agricultural College, Ireland; a=
nd Prof Darius Skarzynski of the Institute of Animal Reproduction and Food =
Research, Polish Academy of Sciences in Olsztyn, Poland. The team also incl=
udes other research students and industry experts.
The Project:
This project will create mathematical models of aspects of the reproductive=
cycle of cows. The techniques used will include systems of ordinary differ=
ential equations, linear algebra, and networks/graphs. Existing models will=
be improved and new models will be developed and studied, based on data pr=
oduced by the Polish partners.
To date there exists a variety of mathematical models of specific hormonal =
responses of individual hormones to other hormone changes, and models depic=
ting a 'broader picture' by simultaneous modelling of behaviour of many hor=
mones and ovarian structures over time. These mathematical models can be us=
ed to investigate in vivo interactions between ovarian structures=92 growth=
, hormone concentration and parameter values (for instance hormone producti=
on or clearance rates). The estrus cycle entails complex interactions and f=
eedback loops between a large number of regulatory factors. The development=
of mathematical models, derived from robust in vitro data and validated in=
vivo, allows us to describe and simulate the normal function of the cycle =
and investigate the mechanisms causing fertility problems or the occurrence=
of double ovulation. The approach allows changing one parameter at a time=
to simulate specific hypothesized mechanisms.
This research project aims to use mathematical modelling to enhance our und=
erstanding of the bovine reproductive cycle, to specifically address:
(1) Describing mechanisms controlling roles of bovine follicles and hormone=
s in double ovulation; and
(2) Investigating the pathways activated/inactivated during atresia using g=
ene regulatory matrices to describe the interaction between genes/proteins =
and hormones.
In addition to mathematical novelty, the attainment of these objectives wou=
ld significantly contribute to advancing the state of knowledge in reproduc=
tive management of cattle, and provides a potential model for exploration o=
f treatments of fertility problems in women.
Please contact Leo Creedon at creedon.leo itsligo.ie for further details.

Dear All,
We will have a seminar Thursday (Oct 10) at 4pm in ADB1020.
Coffee/tea/cakes/biscuits will be served in ADB-G022 from 3:30.
Martin Kerin
from NUIG
will speak on
=E2=80=9CDouble disk-bundles in geometry and topology=E2=80=9D
Abstract: Via a simple topological construction, it is possible to
construct a large class of smooth manifolds, namely, double disk-bundles.
Such spaces both arise naturally in Riemannian geometry and offer natural
candidates for constructing manifolds with interesting geometric
properties. In this talk, I will survey some of the basic ideas behind such
spaces and, motivated by open questions in geometry, study their topology.
Contact: Haixuan Yang
Hoping to see you all there,
Haixuan and Michael

Title: Three essays on stopping
Abstract:
This talk is on my article "three essays on stopping "(https://arxiv.org/ab=
s/1909.13050), where the exponential distribution plays a crucial role, and=
where the focus is on particularly simple proofs of partly known facts. Th=
e audience is only required to have a basic idea about scalar diffusion pro=
cesses and compound Poisson processes.
First, we give a closed-form formula for first passage time of a reflected =
Brownian motion with drift. This modifies a formula by Perry et al (2004). =
Second, we characterize all diffusion processes, where the maximum before a=
fixed draw-down is exponentially distributed. This complements the suffici=
ent condition formulated by Lehoczky (1977). Third, we give a particularly =
simple proof for the fact that the maximum at a fixed drawdown threshold is=
exponentially distributed for any spectrally negative L=E9vy process, a re=
sult due to Mijatovic and Pistorius (2012).
Best regards,
Spyros Dendrinos

TITLE: Sum Functions
ABSTRACT:
Motivated by a problem about reversiblility in groups of formal power serie=
s, I have been thinking about sums such as
1 + 1 + 1 + 1 +=B7=B7=B7,
1 + (1 + 1) + (1 + 1 + 1) + (1 + 1 + 1 + 1)=B7=B7=B7,
1 + (1 + (1 + 1)) + (1 + (1 + 1) + (1 + 1 + 1)) +=B7=B7=B7,
. . .
where 1 =3D 1_K is the multiplicative identity in an integral domain K. I w=
ill talk about this and related matters.

TCD THEORETICAL PHYSICS SEMINAR

Seminar Room, House 20
School of Mathematics
Trinity College Dublin
Speaker: Burkhard Eden (Humboldt University Berlin)
Title: Polylogarithms from the bound state S-matrix
Abstract: Higher-point functions of gauge invariant composite operators
in N=4 super Yang-Mills theory can be computed via triangulation. The
elementary tile in this process is the hexagon introduced for the
evaluation of structure constants. A glueing procedure welding the tiles
back together is needed to return to the original object. In this note
we present work in progress on n-point functions of BPS operators. In
this case, quantum corrections are entirely carried by the glueing
procedure. The lowest non-elementary process is the glueing of three
adjacent tiles by the exchange of two single magnons. This problem has
been analysed before. With a view to resolving some conceptional
questions and to generalising to higher processes we are trying to
develop an algorithmic approach using the representation of
hypergeometric sums as integrals over Euler kernels.
All are welcome.

UCD Algebra and Number Theory Seminar
*Speaker: *Gautier Ponsinet (Bonn)
*Title:* Universal norms and Iwasawa theory
*Abstract:* The problem of universal norms appears in Iwasawa theory,
notably to establish Galois descent result for Selmer groups, known as
''control theorems''. It was first studied by Mazur in his foundational
work on Iwasawa theory for abelian varieties. The problems for abelian
varieties has been solved by Coates and Greenberg. I will explain their
result and its role in Iwasawa theory, and if time allowed, I will talk
about a generalization of their result for p-adic Galois representations.

f"> Understanding Potential Outliers using the O3 Plot.

**Abstract:
Outliers may be important, in error, or irrelevant, but they are=
tricky to identify and deal with. Whether a case is identified as an=
outlier depends on the other cases in the dataset,
on the variables available, and on the criteria used. A case can sta=
nd out as unusual on one or two variables, while appearing middling on the =
others. If a case is identified as an outlier, it is useful to find o=
ut why. This talk discusses the O3 plot (Overview
Of Outliers) for supporting outlier analyses. O3 plots show which ca=
ses are often identified as outliers, which are identified in single dimens=
ions, and which are only identified in higher dimensions. They highli=
ght which variables and combinations of variables
may be affected by possible outliers. Applications include a demogra=
phic dataset for the Bundestag constituencies in Germany and a university r=
anking dataset.**

**Mathematical Modelling of the Bovine Reproductive Cycle**

**The Ideal Candidate:**

Since the project is mathematical modelling based on data from a biological= system, the ideal candidate will have a good honours degree in mathematics= , computing, engineering or science/medicine. Mathematical candidates shoul= d have an interest in biology and biological candidates should have an interest in mathematical modelling. T= he project can be altered somewhat to suit the skills of the successful can= didate. Computing skills are an advantage. Since the successful candidate w= ill be working and publishing as part of an interdisciplinary team, motivation, communication and presentat= ion skills are important.

**The Research Team:**

This research project involves a collaboration between Dr Leo Creedon and D= r Marion McAfee of the Mathematical Modelling Research Group (MMRG) at IT S= ligo, Ireland; Dr Edna Curley, Mountbellew Agricultural College, Ireland; a= nd Prof Darius Skarzynski of the Institute of Animal Reproduction and Food Research, Polish Academy of Scie= nces in Olsztyn, Poland. The team also includes other research students and= industry experts.

**The Project:**

This project will create mathematical models of aspects of the reproductive= cycle of cows. The techniques used will include systems of ordinary differ= ential equations, linear algebra, and networks/graphs. Existing models will= be improved and new models will be developed and studied, based on data produced by the Polish partners.

To date there exists a variety of mathematical models of specific hormonal =
responses of individual hormones to other hormone changes, and models depic=
ting a 'broader picture' by simultaneous modelling of behaviour of many hor=
mones and ovarian structures over
time. These mathematical models can be used to investigate *in vivo interactions between ovarian structures=92 growth, hormone concentration =
and parameter values (for instance hormone production or clearance rates). =
The estrus cycle entails complex interactions
and feedback loops between a large number of regulatory factors. The devel=
opment of mathematical models, derived from robust
in vitro data and validated in vivo, allows us to describ=
e and simulate the normal function of the cycle and investigate the mechani=
sms causing fertility problems or the occurrence of double ovulation. =
The approach allows changing one parameter
at a time to simulate specific hypothesized mechanisms.*

This research project aims to use mathematical modelling to enhance our und= erstanding of the bovine reproductive cycle, to specifically address:

(1) Describing mechanisms controlling roles of bovine follicles and hormone= s in double ovulation; and

(2) Investigating the pathways activated/inactivated during atresia using g= ene regulatory matrices to describe the interaction between genes/proteins = and hormones.

In addition to mathematical novelty, the attainment of these objectives wou= ld significantly contribute to advancing the state of knowledge in reproduc= tive management of cattle, and provides a potential model for exploration o= f treatments of fertility problems in women.

Please contact Leo Creedon at cre= edon.leo itsligo.ie for further details.

Dea= r All,

We w= ill have a seminar Thursday (Oct 10) at 4pm in ADB1020.
