Ph.D. defence: Division Polynomials for Edwards Curves and Divisibility Properties of Kloosterman Sums

Time: 2:30PM
Date: Thu 26th May 2011
Location: CASL Seminar Room - Belfield Office Park [map]

Abstract: Edwards curves have gained attention in recent years for their close connection to elliptic curves. In the first part of this thesis, we investigate the analogue for Edwards curves of the well known division polynomials for elliptic curves. These are recursively defined polynomials
which characterise the torsion points of a given curve.  In the second part of this thesis we derive divisibility results for Kloosterman sums. Using number theoretic results such as Stickelberger's theorem and the Gross-Koblitz formula, we generalise and extend the known divisibility results for these exponential sums.
