In 1955 Jean-Pierre Serre, motivated from Algebraic Geometry, stated his famous conjecture, “We don’t know if there exist finitely generated projective modules over the ring … Read more

## 11 May ~ Jocelyne Ishak “Some topological fun”

This talk is intended to introduce the area of topology to a general audience in a fun way. We will start by defining the notion … Read more

## 23 March ~ José Perusquía “Construction of Random Probability Measures through the Normalisation of Completely Random Measures”

Bayesian Nonparametrics is characterised by “big” parameter spaces and the construction of probability measures on them. For the specification of these (random) probability measures there … Read more

## 9 March ~ Lucy Barnes “Tools for nonlinear PDE’s when numerics won’t save you”

A very brief overview of a variety of tools that can simplify certain nonlinear PDE’s, specifically equations that are difficult to solve numerically. Using conservation … Read more

## 19 Februrary Sibson Seminar Room 3 at 1pm ~ Raf Bocklandt (University of Amsterdam) “Local quivers and Morita theory for matrix factorizations “

We will discuss how techniques in Mirror symmetry developed by Cho, Hong and Lau can lead to a Morita theory for matrix factorizations and tie … Read more

## 16 February ~ Peter Spacek “Canterbury Zoo of Spaces, an overview of the main subfields of Differential Geometry”

This presentation will give a short tour through the Canterbury Zoo of Spaces, i.e. it will introduce the basics and some nice examples and applications … Read more

## 9 February ~ Aniketh Pittea, Alexandra Rogers and Alan Riva Palacio “Some open problems and questions”

Alex will present a problem on the invariant factors of certain types of matrices arising from diagrams. Aniketh will discuss graphical models and the controversies … Read more

## 2 February ~ Isaac Oppong “Balance Incomplete Block Designs (BIBDs) in the Splitting Fields of some Polynomials”

We consider how we can obtain balance incomplete block designs (BIBDs) from the splitting fields of some class of polynomials. The splitting field of polynomial, … Read more

## 26 January ~ Andrew Celsus (University of Cambridge) “Asymptotics of Orthogonal Polynomials with Respect to Varying Complex Weights”

Motivated by the numerical approximation of highly oscillatory integrals, we consider asymptotics of orthogonal polynomials with respect to varying complex weights. The zeros of these … Read more

## 15 December ~ Hélder Lima “An introduction to (multiple) orthogonal polynomials”

In this talk we will see the definitions and some basic results, examples and applications for orthogonal polynomials, multiple orthogonal polynomials and d-orthogonal polynomials.
