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 is 's comatri…
Quelques remarques sur le champ des courbes hyperelliptiques en caracteristique deux
Jose Bertin
Dans cette note on decrit le champ des courbes hyperelliptiques lisses defines sur un corps algebriquement clos de caracteristique deux comme un champ quotient. On en deduit le gro…
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…
On the Kontsevich-Kuperberg-Thurston construction of a configuration-space invariant for 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…
Complete Intersection Lattice Ideals
Marcel Morales, Apostolos Thoma
In this paper we completely characterize lattice ideals that are complete intersections or equivalently complete intersections finitely generated semigroups of $\bz^n\oplus T$ with…
