DESCRIPTION:Tobias Rossmann (NUI Galway)\nOver the past decades\, the stud
y of zeta functions arising from algebraic counting problems has evolved i
nto a distinct branch of asymptotic algebra. An appealing feature of this
area is that it constitutes a meeting ground for several different mathema
tical subjects such as algebra\, combinatorics\, geometry\, and logic. The
first part of my talk will be a (biased) introduction to this area\, in p
articular to the study of zeta functions enumerating subobjects (e.g. subg
roups). I will then turn to recent developments surrounding the enumeratio
n of (linear) orbits of unipotent groups. A key theme will be the developm
ent of tools for proving the absence or presence of geometric features in
(at first glance) unexpected places.
