CUDA-MPQS: A GPU-Resident Self-Initializing Quadratic Sieve, and the Factorization of RSA-155

Fabian Januszewski, Christoph Heinrichs

The quadratic sieve (QS) is an irregular, cache-hostile, branch-heavy integer factorization algorithm; prior GPU work accelerates individual stages of it. We present \swname{}, a s…

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 space…

Locally algebraic representations and integral structures on the cohomology of arithmetic groups

Fabian Januszewski

This paper introduces the notion of locally algebraic representations and corresponding sheaves in the context of the cohomology of arithmetic groups. These representations are of…

Towards a tensor-classification of Harish-Chandra modules: The case

Fabian Januszewski

We consider the category of Harish-Chandra modules for as a module over the category of finite-dimensional representations of with respect to…

Families of twisted -modules and arithmetic models of Harish-Chandra modules

Takuma Hayashi, Fabian Januszewski

We develop a theory of tdos and twisted -modules over general base schemes with a focus on functorial aspects. In particular, we introduce a flat base change functor an…

-functions of -adic properties and non-vanishing of twists

Mladen Dimitrov, Fabian Januszewski, A. Raghuram

The principal aim of this article is to attach and study -adic -functions to cohomological cuspidal automorphic representations of over a totally real f…

Non-abelian -adic Rankin-Selberg -functions and non-vanishing of central -values

Fabian Januszewski

We prove new congruences between special values of Rankin-Selberg -functions for over arbitrary number fields. This allows us to control t…

On Period Relations for Automorphic L-functions II

Fabian Januszewski

We study Hecke algebras for pairs over arbitrary fields of characteristic , define the Bernstein functor and give another definition of the Zuckerman fun…

On Period Relations for Automorphic L-functions I

Fabian Januszewski

This paper is the first in a series of two dedicated to the study of period relations of the type $$ L(\frac{1}{2}+k,Π)\;\in\;(2πi)^{d\cdot k}Ω_{(-1)^k}{\mathbb Q}(Π),\quad \frac{1…

p-adic L-functions for Rankin-Selberg convolutions over number fields

Fabian Januszewski

We unconditionally construct cyclotomic p-adic L-functions for Rankin-Selberg convolutions for GL(n+1) x GL(n) over arbitrary number fields, and show that they satisfy an expected…

Rational Structures on Automorphic Representations

Fabian Januszewski

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 o…

Algebraic Characters of Harish-Chandra Modules and Arithmeticity

Fabian Januszewski

These are expanded notes from lectures at the Workshop "Representation Theory and Applications" held at Yeditepe University, Istanbul, in honor of Roger E. Howe. They are supplemen…

Algebraic Characters for Harish-Chandra modules

Fabian Januszewski

We give a cohomological treatment of a character theory for (g,K)-modules. This leads to a nice formalism extending to large categories of not necessarily admissible (g,K)-modules.…

On p-adic L-functions for over totally real fields

Fabian Januszewski

We refine and extend previous constructions of -adic -functions for Rankin-Selberg convolutions on $\GL(n)\times\GL(n-1)$ for regular algebraic representations over totally r…

Modular symbols for reductive groups and p-adic Rankin-Selberg convolutions over number fields

Fabian Januszewski

We give a construction of a wide class of modular symbols attached to reductive groups. As an application we construct a p-adic distribution interpolating the special values of the…
