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…
Vector partition function and generalized Dahmen-Micchelli spaces
C. De Concini, C. Procesi, M. Vergne
This is the first of two papers on partition functions and the index theory of transversally elliptic operators. In this paper we only discuss algebraic and combinatorial issues re…
The quotient of a complete symmetric variety
Corrado De Concini, Senthamarai Kannan, Andrea Maffei
We study the quotient of a completion of a symmetric variety G/H under the action of H. We prove that this is isomorphic to the closure of the image of an isotropic torus under the…
