Equivariant derived category of a complete symmetric variety

Stéphane Guillermou

Let G be a complex algebraic semi-simple adjoint group and X a smooth complete symmetric G-variety. Let L_i be the irreducible G-equivariant intersection cohomology complexes on X,…

Jordan Normal and Rational Normal Form Algorithms

Bernard Parisse, Morgane Vaughan

In this paper, we present a determinist Jordan normal form algorithms based on the Fadeev formula: \[(λ\cdot I-A) \cdot B(λ)=P(λ) \cdot I\] where $B (λ)$ is $(λ \cdot I - A)$ 's comatri…

Fractional Moment Estimates for Random Unitary Operators

Alain Joye

We consider unitary analogs of $d -$ dimensional Anderson models on $l^{2} (Z^{d})$ defined by the product $U_{ω} = D_{ω} S$ where $S$ is a deterministic unitary and $D_{ω}$ is a diagonal matrix…

Splitting formulae for the Kontsevich-Kuperberg-Thurston invariant of rational homology 3-spheres

Christine Lescop

M. Kontsevich proposed a topological construction for an invariant Z of rational homology 3-spheres using configuration space integrals. G. Kuperberg and D. Thurston proved that Z…

Jump formulas in Hamiltonian Geometry

Paul-Emile Paradan

This paper is concerned with the Hamiltonian actions of a torus on a symplectic manifold. We are interested here in two global invariants: the Duistermaat-Heckman measure DH(M), an…
