Motivic action on coherent cohomology of Hilbert modular varieties
Aleksander Horawa
4:30pm|Simonyi Hall 101 and Remote Access

A surprising property of the cohomology of locally symmetric spaces is that Hecke operators can act on multiple cohomological degrees with the same eigenvalues. We will discuss this phenomenon for the coherent cohomology of line bundles on modular...

The vision of the sets according to Brownian travelers
6:00pm|Birch Garden, Simons Hall

The harmonic measure is an important tool, which allows one to reconstruct a harmonic function from its values on the boundary. But it also admits a very simple and beautiful probabilistic interpretation: it is the probability that the path of the...

Arithmetic Groups

Profinite Completions and Representation Rigidity
Ryan Spitler
11:00am|Simonyi 101 and Remote Access

Taking up the terminology established in the first lecture, in 1970 Grothendieck showed that when two groups $(G,H)$ form a Grothendieck pair, there is an equivalence of their linear representations. For recent work showing that certain groups are...

Euler flows with local energy dissipation
2:00pm|Simonyi Hall 101 and Remote Access

The incompressible 3D Euler equations have total kinetic energy conservation for smooth (spatially periodic) solutions. In the recent resolution of the Onsager conjecture by Isett, on the other hand, below certain threshold Hölder regularity, Euler...
