Local theta correspondence and Galois periods

Chong Zhang

We study the behavior of Galois periods under the local theta correspondence for even orthogonal and symplectic groups. Specifically, we compare their multiplicities and construct…

The super approximation property of $SL_{2} (Z / q Z) \times SL_{2} (Z / q Z) \times SL_{2} (Z / q Z)$

Chong Zhang

Take $S \subset SL_{2} (Z) \times SL_{2} (Z) \times SL_{2} (Z)$ be finite symmetric and assume $S$ generates a group $G$ which is Zarisk…

Characterizations of annihilator $(b, c)$ -inverses in arbitrary rings

Chong-Quan Zhang, Qing-Wen Wang, Huihui Zhu

In this paper, we investigate some properties of annihilator $(b, c)$ -inverses in an arbitrary ring. We demonstrate that one-sided annihilator $(b, c)$ -inverses of elements in arbitr…

Theta lifts and distinction for regular supercuspidal representations

Chong Zhang

This article has a twofold purpose. First, by recent works of Kaletha and Loke-Ma, we give an explicit description of the local theta correspondence between regular supercuspidal r…
