Abstract

We describe the enhanced Langlands parameters of the irreducible constituents of a regular principal series of a quasi-split reductive group over a non-archimedean local field of characteristic zero. Starting from the chamber parametrization by Rodier and Luo, we determine the monodromy of each constituent and show that its enhancement is trivial. In particular, we obtain the corresponding parameter of the unique irreducible subrepresentation.

On the $θ$-split side of the local relative trace formula

The author derives an expression for one side of the local relative trace formula, at the level of Lie algebras, by combining methods of Arthur and Harish-Chandra with the structure theory for reductive symmetric spaces.

Semi-infinite parabolic IC-sheaf II: the Ran space version

This paper is a sequel to arXiv:2310.0638. Let G be a split reductive group. We define the parabolic semi-infinite category on the Ran version of the affine Grassmanian Gr_{G,Ran}. We study the semi-infinite parabolic IC-sheaf in this category. We provide several descriptions of this object, one as certain colimit, another as an intermediate extension in certain category. We relate the global and local semi-infinite categories of sheaves. We also relate the intersection cohomology sheaf of the Drinfeld compactification of Bun_P with the semi-infinite parabolic IC-sheaf.

Unipotent representations and the categorical trace of Frobenius

We give a new proof of the classification of unipotent representations for split finite groups of Lie type. To do this, we first construct an (infinity, 2)-categorification of Lusztig's map from the Hecke algebra to the asymptotic algebra. Then we use the theory of weights to show that it induces an isomorphism after applying trace of Frobenius.
