On the global dynamics of Maxwell-Klein-Gordon equations »

Shiwu Yang, Peking University
2pm 2 April 2019

It is conjectured that for the Maxwell-Klein-Gordon equations having data with non-vanishing charge and arbitrary large size, the global solutions disperse as linear waves and enjoy the so-called peeling properties for pointwise estimates. We give a gauge independent proof of the conjecture.

Delta-rings »

Dr James Borger (MSI)
3pm 29 March 2019

I'll introduce the basic theory of delta-rings, which are one of the key ingredients in prismatic cohomology.

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.

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.
