A hereditary theorem for rigid and pseudorigid components of Lusztig's nilpotent varieties in type

Erez Lapid, Mark Shusterman

For irreducible components of Lusztig's nilpotent varieties of type with graded dimension arising from permutations , we characteriz…

A greedy open-orbit criterion for solvable algebraic group actions, with applications to Lusztig's nilpotent varieties

Erez Lapid

Let be a connected solvable algebraic group acting rationally on a finite-dimensional vector space . Using a -stable complete flag, we formulate a successive-quotient pro…

On an inequality of Bushnell--Henniart for Rankin--Selberg conductors

Erez Lapid

We prove a division algebra analogue of an ultrametric inequality of Bushnell--Henniart for Rankin--Selberg conductors. Under the Jacquet--Langlands correspondence, the two version…

On the meromorphic continuation of Eisenstein series

Joseph Bernstein, Erez Lapid

Eisenstein series are ubiquitous in the theory of automorphic forms. The traditional proofs of the meromorphic continuation of Eisenstein series, due to Selberg and Langlands, star…

Explicit Plancherel formula for the space of symplectic forms

Erez Lapid, Omer Offen

We provide a Plancherel decomposition for the space of symplectic bilinear forms of rank over a local non-archimedean field in terms of that of .

On the distinguished spectrum of with respect to

Erez Lapid, Omer Offen

Given a reductive group and a reductive subgroup , both defined over a number field , we introduce the notion of the -distinguished automorphic spectrum of and ana…
