The rectangle graph
Claudio Procesi
We go back to a graph used extensively in previous papers with Michela Procesi and Bich Van Nguyen to studi the non linear Scroginger equation. We fix several mistakes of that trea…
Box splines and the equivariant index theorem
C. De Concini, C. Procesi, M. Vergne
In this article, we start to recall the inversion formula for the convolution with the Box spline. The equivariant cohomology and the equivariant K-theory with respect to a compact…
Infinitesimal index: cohomology computations
Corrado De Concini, Claudio Procesi, Michele Vergne
In this note several computations of equivariant cohomology groups are performed. For the compactly supported equivariant cohomology, the notion of infinitesimal index developed in…
The infinitesimal index
Corrado de Concini, Claudio Procesi, Michele Vergne
In this note, we study an invariant associated to the zeros of the moment map generated by an action form, the infinitesimal index. This construction will be used to study the comp…
Vector partition functions and index of transversally elliptic operators
Corrado De Concini, Claudio C. Procesi, Michele Vergne
Let G be a torus acting linearly on a complex vector space M, and let X be the list of weights of G in M. We determine the equivariant K-theory of the open subset of M consisting o…
A curious identity and the volume of the root spherical simplex
C. De Concini, C. Procesi
We show a curious identity on root systems which gives the evaluation of the volume of the spherical simpleces cut by the cone generated by simple roots.
