A non-selfdual automorphic representation of GL3 and a Galois representation

open access: yesInventiones Mathematicae, 1994
Given the congruence subgroup \(\Gamma_0 (N)\) of \(\text{SL}_2 (\mathbb Z)\) the first étale cohomology group \(H^1 (X_0 (N)_{\overline {\mathbb Q}}, \mathbb Q_\ell)\) of the associated modular curve \(X_0 (N)\) gives rise to a certain Galois representation (i.e.

New Zero-Density Results for Automorphic L-Functions of GL(n)

open access: yesMathematics, 2021
Let L(s,π) be an automorphic L-function of GL(n), where π is an automorphic representation of group GL(n) over rational number field Q. In this paper, we study the zero-density estimates for L(s,π).

Chow groups and L-derivatives of automorphic motives for unitary groups, II.

open access: yesForum of Mathematics, Pi, 2022
In this article, we improve our main results from [LL21] in two directions: First, we allow ramified places in the CM extension $E/F$ at which we consider representations that are spherical with respect to a certain special maximal compact subgroup, by ...

PERIOD IDENTITIES OF CM FORMS ON QUATERNION ALGEBRAS

open access: yesForum of Mathematics, Sigma, 2020

Representations of automorphism groups on the homology of matroids [PDF]

open access: yesEuropean Journal of Combinatorics, 2021
Given a group $G$ of automorphisms of a matroid $M$, we describe the representations of $G$ on the homology of the independence complex of the dual matroid $M^*$. These representations are related with the homology of the lattice of flats of $M$, and (when $M$ is realizable) with the top cohomology of a hyperplane arrangement.

An Integral Representation of Standard Automorphic L Functions for Unitary Groups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
Let F be a number field, G a quasi-split unitary group of rank n. We show that given an irreducible cuspidal automorphic representation π of G(A), its (partial) L function LS(s,π,σ) can be represented by a Rankin-Selberg-type integral involving cusp ...

Rational structures on automorphic representations [PDF]

open access: yesMathematische Annalen, 2017
This paper proves the existence of global rational structures on spaces of cusp forms of general reductive groups. We identify cases where the constructed rational structures are optimal, which includes the case of GL($n$). As an application, we deduce the existence of a natural set of periods attached to cuspidal automorphic representations of GL($n$).
