Betti-Whittaker periods of the contragredient representations for

Yubo Jin, Dongwen Liu, Binyong Sun

We define Betti-Whittaker periods for a broad class of cohomological automorphic representations and establish a relation between the periods associated with these representations…

On Deligne's conjecture for Hecke characters

Yubo Jin, Dongwen Liu, Binyong Sun

This paper provides a proof of Deligne's conjecture for critical values of Hecke L-functions following a strategy originated by Harder and Schappacher.

Period relations for Rankin-Selberg convolutions for

Yubo Jin, Jian-Shu Li, Dongwen Liu +1

Using the modular symbol approach, we prove the rationality and period relations for certain critical values of Rankin-Selberg L-functions for

On the Blasius-Deligne conjecture for the standard -functions of symplectic type for

Dihua Jiang, Dongwen Liu, Binyong Sun +1

In this paper we give an unconditional proof of the Blasius-Deligne conjecture for the critical values of the -standard -functions of symplectic type with $n\g…

Hausdorffness of certain nilpotent cohomology spaces

Fabian Januszewski, Binyong Sun, Hao Ying

Let be a smooth representation of a compact Lie group on a quasi-complete locally convex complex topological vector space. We show that the Lie algebra cohomology spac…

On rationality of certain Eisenstein cohomology

Yubo Jin, Dongwen Liu, Binyong Sun

In this paper, we study the Eisenstein cohomology coming from Eisenstein series associated to degenerate principal series representations and prove certain rationality result.
