Finite simple semirings

Time: 4:00PM
Date: Mon 19th September 2011
Location: Mathematical Sciences Seminar Room [map]

Abstract: Abstract: Chris Monico showed in 2004 that for a classification of all
finite simple semirings, it will be sufficient to classify all finite simple
additively idempotent semirings. In this talk, we try to characterize every
finite simple additively idempotent semiring as a semiring of join-morphisms
of a semilattice. We succeed in doing this for a large class of semirings,
however some very specific structures are not covered by our approach. These
will also be discussed in the talk.

(This talk is part of the Algebra and Number Theory series.)
