We give alternative computations of the Schur multiplier of $Sp(2g,\mathbb Z/D\mathbb Z)$, when $D$ is divisible by 4 and $g\geq 4$: a first one using $K$-theory arguments based on the work of Barge and Lannes and a second one based on the Weil repre

Let M be a compact oriented three-manifold whose interior is hyperbolic of finite volume. We prove a variation formula for the volume on the variety of representations of π 1 ( M ) in SL n ( ℂ ) . Our proof follows the strategy of Reznikov’s rig

Conjugation spaces are topological spaces equipped with an involution such that their fixed points have the same mod $2$ cohomology (as a graded vector space, a ring, and even an unstable algebra) but with all degrees divided by two, generalizing the

This volume presents an elaborated version of lecture notes for two advanced courses: (Re)Emerging methods in Commutative Algebra and Representation Theory and Building Bridges Between Algebra and Topology, held at the CRM in the spring of 2015.
This book includes 33 expanded abstracts of selected talks given at the two workshops'Homological Bonds Between Commutative Algebra and Representation Theory'and'Brave New Algebra: Opening Perspectives,'and the conference'Opening Perspectives in Alge

We study the relationship between trivial cocycles on the Torelli group and invariants of oriented integral homology 3-spheres. We give ncecessary and sufficient conditions for a function defined on the union of the Torelli groups to be an invariant

The mapping class group of an oriented surface Σg, 1 of genus g with one boundary component has a natural decreasing filtration Mg,1 ⊃ Mg,i(⊃) 3 Me , i(⊃) D M g,1 (3) ⊃..., where M g,1 (k) is the kernel of the action of M g,1 on the k th nil

For closed oriented manifolds, we establish oriented homotopy invariance of higher signatures that come from the fundamental group of a large class of orientable 3-manifolds, including the ``piecewise geometric'' ones in the sense of Thurston. In par
