Events - January 2016

Ian Payne, Department of Pure Mathematics,  University of Waterloo

“A result on constraint satisfaction problems: part 2”

Jonathan Stephenson, Department of Pure Mathematics, University of Waterloo

“Lowness Notions”

We will continue our study of the relationships between different lowness notions. Each such notion captures the idea of a real number having minimal computational power according to some criterion.

Raymond Cheng, Department of Pure Mathematics, University of Waterloo

“Hilbert Objects, First Examples”

I will reveal the secrets of the Hilbert function, speak of the Hilbert polynomial and then talk more about the Hilbert scheme. As an example of a Hilbert scheme, we talk about the Grassmannian.

“More on the Beurling-Selberg function”

Anton Borissov, Department of Pure Mathematics, University of Waterloo

“Conformal Field Theory: A Worker’s Perspective”

Matthew Moore, Vanderbilt University

“Absorption and directed Jonsson terms”

Jonathan Stephenson, Department of Pure Mathematics, University of Waterloo

“Lowness Properties”

AbstractGiven a class C of real numbers which can be relativized to a class C(X) depending on a real parameter X, we say that X is low for C if C(X)=C.

Raymond Cheng, Department of Pure Mathematics, University of Waterloo

“Points in the Plane”

Nothing too fancy today: let us simply study schemes supported on finite subsets of the complex plane. Along the way, we will talk about Hilbert functions, Hilbert polynomials, families of schemes and maybe even something about moduli.

Deirdre Haskell, McMaster University

will speak about

“Overview II ”

Abstract

We continue with the introduction to Ducros’ Bourbaki paper on Berkovich spaces (after Hrushovski and Loeser).
