Geometries of groupsProf. Christian RosendalUniversity of Illinois at ChicagoTime: 03:45 PMColloquium Series
View Abstract
Geometric group theory or more precisely large scale geometry of discrete groups is based on the fundamental observation that the word metrics on a discrete group given by distinct finite generating sets are biLipschitz equivalent, i.e., differ at most by a multiplicative constant. This observation permits treating finitely generated groups as geometric objects as long as the methods employed are insensitive to the multiplicative error and has led to a very rich interplay between numerous mathematical disciplines such as algebra, topology, functional and harmonic analysis, ergodic theory and logic. Moreover, this study carries quite easily over to compactly generated locally compact groups, but so far more general topological transformation groups, e.g., homeomorphism and diffeomorphism groups, have resisted treatment from this perspective due to the presumed absence of canonical generating sets. We shall present some newly developed tools for overcoming this. The talk will be aimed at a general audience.

Two Tales of FreenessProf. Michael DiPasqualeOklahoma State UniversityTime: 03:45 PMColloquium Series
View Abstract
A graded module over a polynomial ring is free if it has a set of generators so that every module element can be written uniquely as a polynomial combination of the given generators. This is the algebraic analog of a vector bundle over projective space splitting completely. I will discuss two contexts in which freeness plays a crucial role. The first, from approximation theory, is the module of piecewise polynomial functions (splines) over a fixed subdivision. The second, from the theory of hyperplane arrangements, is the module of derivations. Classical work on freeness in these contexts contains a beautiful interplay between combinatorial and geometric features, which we will spend most of the talk exploring. Towards the end we will discuss recent work on connections between splines and hyperplane arrangements.
