We will discuss de Rham and Hyodo-Kato flip-flopping for dual towers of rigid analytic spaces. The main tools are comparison theorems expressing the two cohomologies as pro-étale cohomologies of corresponding relative period sheaves that, by...

A deep result of Furstenberg from 1967 states that if $\Gamma$ is a lattice in a semisimple Lie group $G$, then there exists a measure on $\Gamma$ with finite first moment such that the corresponding harmonic measure on the Furstenberg boundary of...

A dictionary data structure maintains a set of at most $n$ keys from the universe $[U]$ under key insertions and deletions, such that given a query $x\in[U]$, it returns if $x$ is in the set. Some variants also store values associated to the keys...

In my recent work on a geometric proof of the endoscopic fundamental lemma for spherical Hecke algebras, there are many new features not present in its Lie algebra analogue originally proved by B.C.~Ng\^o. One of such new features is an asymptotic...

A matrix M is rigid if one needs to change it in many places in order to reduce its rank significantly. While a random matrix M (say over a finite field) is rigid with high probability, coming up with explicit constructions of such matrices is still...

Topological Hochschild homology is an important invariant, closely related to algebraic K-theory, and can be seen as a noncommutative analogue of de Rham chains.

In this talk, I will describe various computations of the ring/monoid of endomorphisms...
