The WZ pair and finite congruences

Xiang Chen, Junyan Liu, Hengfei Lu

We construct a meromorphic Wilf--Zeilberger pair for the hypergeometric series for \(3\ln 2\), completing the WZ proof left open by Guillera and Rogers. The same pair yields a one-…

Multiplicity one for the pair (GL(n,D),GL(n,E))

Hengfei Lu

Let F be a local field of characteristic zero. Let D be a quaternion algebra over F. Let E be a quadratic field extension of F. Let μ be a character of GL(1,E). We study the distin…

The action of a mirabolic subgroup on a symmetric variety

Hengfei Lu

Let F be a local field of character zero. Let E be a quadratic field extension of F. We show that any P-invariant linear functional on a GL(n,E)-distinguished irreducible smooth ad…

The Siegel-Weil formula for unitary groups: the second term range

Hengfei Lu

We study the Siegel-Weil formula in the second term range () for unitary groups of hermitian forms over a skew-field with involution of the second kind.

The distinction problem for metaplectic case

Hengfei Lu

We use the theta lifts between Mp(2) and PD to study the distinction problems for the pair (Mp(2,E), SL(2,F )), where E is a quadratic field extension over a nonarchimedean local f…

Some applications of theta correspondence to branching laws

Hengfei Lu

In this paper, we will use the local theta correspondences for the dual pair (Sp(W),O(V)) to investigate some branching law problems.
