## 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.

## 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.
