ANALYSIS SEMINAR
TIME: 3:35 – 4:25
ROOM: AYRES 209A
SPEAKER: Professor Remus Nicoara
ABSTRACT: Commuting squares arise naturally as invariants and construction data in Jones' theory of subfactors. We investigate some existence and finiteness results for commuting squares and their associated subfactors with emphasis on those arising from complex Hadamard matrices.

COLLOQUIUM
TIME: 3:40 -- 4:25
ROOM: Ayres 214
SPEAKER: Professor Nikolay Brodskiy (tenure candidate)
TITLE: Asymptotic dimensions of groups and spaces
ABSTRACT: I will talk about the large scale geometry of unbounded metric spaces, such as complete open Riemannian manifolds, and their global properties where small (bounded) details can be disregarded. One investigates the properties which are defined by taking the limit at infinity. This provides an analogy between the large scale world and the small scale world, where one takes the limit at 0. The basic ideas of large scale dimension theory were introduced by Gromov. I will describe asymptotic invariants of a metric space (in particular, of a finitely generated group) related to asymptotic dimension.
