Compactification of Lie Groups »

Professor Richard Melrose, Massachusetts Institute of Technology (MIT)
2pm 29 March 2019

I will discuss compactifications of semisimple Lie groups, in particular SU(n) over the real and complex fields, as manifolds with corners.

Chebyshev polynomials, Lehmer numbers, and huge primes »

Prof Andrew Hone, University of Kent
4pm 28 March 2019

We consider the appearance of prime numbers in a family of linear recurrence sequences, labelled by a positive integer n.

Lower bound of the Riesz transform kernel on Stratified Lie groups, commutators and applications »

Ji Li, Macquarie University
2pm 26 March 2019

The commutator of the Riesz transform (Hilbert transform in dimension 1) and a symbol $b$ is bounded on $L^2(\mathbb R^n)$ if and only if $b$ is in the BMO space BMO$(\mathbb R^n)$ (Coifman--Rochberg--Weiss). It is natural to ask whether it holds for commutator of Riesz transform on Heisenberg groups.

Axially asymmetric traveling fronts in balanced bistable reaction-diffusion equations »

Masaharu Taniguchi, Okayama University
11am 22 March 2019

For a balanced bistable reaction-diffusion equation, an axisymmetric traveling front has been well known. We prove that an axially asymmetric traveling front with any positive speed does exist in a balanced bistable reaction-diffusion equation.

Honeycombs and polytopes: another look at representation theory »

Prof Robert Coquereaux, Universite de Marseille, Luminy
4pm 21 March 2019

After introducing several geometrical models that can be used to calculate multiplicities in Lie group theory, we describe associated polytopes whose volumes can be considered as approximations of those multiplicities.

Stacks, gerbes, and T-duality »

12pm 21 March 2019

A brief introduction to stacks,  bundle gerbes and their applications to T-dualities. Many examples will be presented so the talk should be accessible to anyone to some background in differential geometry and algebraic topology.

The marked length spectrum of Anosov manifolds »

Colin Guillarmou, University of Paris-Sud (Orsay)
2pm 19 March 2019

We show some new rigidity result for the marked length spectrum of closed negatively curved manifolds.
