"Introduction to the seminar"

This is the first, introductory lecture to a learning seminar on discrete
homotopies for binary reflexive digraphs and their application to finite
relational structures. In this lecture I will briefly overview the idea
of homotopy, state Taylor's theorem (that the existence of continuous

"Space of completely bounded Lp multipliers and its pre-dual"

Let G be a locally compact group. G. Pisier considered the operator space

Chung Pang Mok, McMaster University

"Endoscopic classification of automorphic representations on classical groups"

The recent work of Arthur on classification of automorphic
representations on classical groups is a landmark result in the Langlands'
program. In this talk we will try to indicate the nature of the
classification and the tools that are used in the proof.

Refreshments will be served in MC 5046 at 3:30.

"Definition and basic properties of homotopy groups"

“Getting a handle on surfaces”

The 2-sphere, a torus, a projective plane and a Klein bottle are examples of closed surfaces (or 2-manifolds) that are all distinct in the sense that none of the four admit homeomorphisms to any of the others. This begs the question: which distinct surfaces are able to exist and can we classify them?

“Strong irregularity of the trace class convolution algebra”

For a locally compact quantum group G, the space T(L2(G)) of trace class operators on L2(G) is a completely contractive Banach algebra with the multiplication induced by the right fundamental unitary of G. We will discuss the strong Arens irregularity (in the sense of Dales- Lau) of this convolution algebra.

“Balanced metrics on ruled manifolds”

In 2001, Donaldson proved that the existence of cscK metrics on a polarized manifold (X,L) with discrete automorphism group implies existence of balanced metrics on Lk for k large enough. We show that a similar statement holds if one twists the line bundle L with a simple stable vector bundle E.

"Groups in topological algebras"

Tom Ramsey, University of Hawaii

“Kronecker Constants”

Recent progress will be described, with a focus on exact constants for finite sets of integers. There is now a complete analysis of integer sets where successive terms grow by a constant ratio. There are also interesting and close upper and lower bounds for the Kronecker constants of initial segments of the positive integers.

"Some model theory of fields with operators"

The model theory of fields, usually with additional structure (such as a derivation or an automorphism) is the primary (but not solitary) locus of interaction between model theory and algebraic geometry.
