L-modules are mixed
Leslie Saper
Let X be the locally symmetric space associated to a reductive -group G and an arithmetic subgroup . An L-module M is a combinatorial model of a constructible complex…
Perverse sheaves and the reductive Borel-Serre compactification
Leslie Saper
We briefly introduce the theory of perverse sheaves with special attention to the topological situation where strata can have odd dimension. This is part of a project to use perver…
The fundamental group of reductive Borel-Serre and Satake compactifications
Lizhen Ji, V. Kumar Murty, Leslie Saper +1
Let be an almost simple, simply connected algebraic group defined over a number field , and let be a finite set of places of including all infinite places. Let b…
L^2-cohomology of locally symmetric spaces, I
Leslie Saper
Let X be a locally symmetric space associated to a reductive algebraic group G defined over Q. L-modules are a combinatorial analogue of constructible sheaves on the reductive Bore…
On the Cohomology of Locally Symmetric Spaces and of their Compactifications
Leslie Saper
This expository article is an expanded version of talks given at the "Current Developments in Mathematics, 2002" conference. It gives an introduction to the (generalized) conjectur…
Geometric rationality of equal-rank Satake compactifications
Leslie Saper
Satake has constructed compactifications of symmetric spaces D=G/K which (under a condition called geometric rationality by Casselman) yield compactifications of the corresponding…
