Intertwining Operators for Siegel Parabolics over Finite Fields

Nir Elber, Hahn Lheem

We consider degenerate principal series representations $Ind_{P}^{G} χ$ over finite fields, where $G$ is a classical subgroup of $GL_{2 n}$ , and $P$ is the…

Explicit Computations of Fundamental Classes

Nir Elber

We use the techniques of group cohomology to give explicit computations of the local fundamental class. As an application, we discuss how to compute the Tate canonical class for th…

Generalized Periodicity in Group Cohomology

Nir Elber

Given a finite group $G$ , we introduce "encoding pairs," which are a pair of $G$ -modules $M$ and $M^{'}$ equipped with a shifted natural isomorphism between the cohomological functors…

Prime Sums

Anupam Datta, Nir Elber, Raymond Feng +2

We study the properties of certain graphs involving the sums of primes. Their structure largely turns out to relate to the distribution of prime gaps and can be roughly seen in Cra…
