The algebraic theory of non-archimedean intertwining periods

Fei Chen, Nadir Matringe

We develop an algebraic theory of local intertwining periods for symmetric pairs $(G, H, θ)$ over non-archimedean local fields $F$ of characteristic different from $2$ , and finite-le…

Relative Bruhat decomposition of wonderful compactification

Fei Chen, Shang Li

In the seminal paper of Borel and Tits about reductive groups, they show some fundamental results about Bruhat cells with respect to a minimal parabolic subgroup, e.g., relative Br…

Spectral transfer for metaplectic groups. II. Hecke algebra correspondences

Fei Chen, Wen-Wei Li

Let $Mp (2 n)$ be the metaplectic group over a local field $F \supset Q_{p}$ defined by an additive character of $F$ of conductor $4 o_{F}$ . Gan-Savin ($p \ne…

Commutation of transfer and Aubert-Zelevinski involution for metaplectic groups

Fei Chen

A result of K. Hiraga says endoscopic transfer is compatible with Aubert-Zelevinski involution. In this short note, we generalize Hiraga's result to metaplectic group setting.

Intertwining operators in the Takeda-Wood isomorphism

Fei Chen, Wen-Wei Li

Over any non-Archimedean local field of characteristic not equal to $2$ , Takeda and Wood constructed types for the two blocks containing the even and odd Weil representations of th…
