Modularity of higher theta series I: cohomology of the generic fiber
Tony Feng, Zhiwei Yun, Wei Zhang
In a previous paper we constructed higher theta series for unitary groups over function fields, and conjectured their modularity properties. Here we prove the generic modularity of…
A Deligne-Simpson problem for irregular -connections over
Konstantin Jakob, Zhiwei Yun
We give an algebraic and a geometric criterion for the existence of -connections on with prescribed irregular type with equal slope at (isoclinic) and…
Tilting sheaves for real groups and Koszul duality
Andrei Ionov, Zhiwei Yun
For a certain class of real analytic varieties with Lie group actions we develop a theory of (free-monodromic) tilting sheaves, and apply it to flag varieties stratified by real gr…
Functions on the commuting stack via Langlands duality
Penghui Li, David Nadler, Zhiwei Yun
We calculate the dg algebra of global functions on commuting stacks of complex reductive groups using tools from Betti Geometric Langlands. In particular, we prove that the ring of…
