A note on small theta lift

Jingsong Chai

In this note, we use certain sesquilinear form to realize small theta lift for even orthogonal-symplectic and unitary dual pairs over p-adic fields.

On parabolic induction and Jacquet modules over p-adic group

Jingsong Chai

In this note, using tensor products with appropriate bimodules over Hecke algebras, we uniformly describe parabolic induction and Jacquet module. We also recover a result of Loke a…

Asai gamma factors over finite fields

Jingsong Chai

In this note, we define and study Asai gamma factors over finite fields. We also prove some results about local Asai L-functions over p-adic fields for level zero representations.

A strong multiplicity one theorem for SL(2)

Jingsong Chai, Qing Zhang

It is known that multiplicity one property holds for SL(2), while the strong multiplicity one property fails. However, in this paper, we show that if we require further that a pair…
