Chern character for twisted K-theory of orbifolds
Jean-Louis Tu, Ping Xu
For an orbifold X and , we introduce the twisted cohomology and prove that the Connes-Chern character establishes an isomorphism between the twisted K…
On finite range stable type concentration
J. C. Breton, C. Houdré
The purpose of these notes is to further complete our understanding of the stable concentration phenomenon, by obtaining the finite range behavior of , with $F=f(X…
Concentration of the Brownian bridge on Cartan-Hadamard manifolds with pinched negative sectional curvature
Marc Arnaudon, Thomas Simon
We study the rate of concentration of a Brownian bridge in time one around the corresponding geodesical segment on a Cartan-Hadamard manifold with pinched negative sectional curvat…
Orbites Nilpotentes Sphériques et Représentations unipotentes associées : Le cas
Hervé Sabourin
Let be a real simple Lie group, $\got g$ its Lie algebra. Given a nilpotent adjoint -orbit , the question is to determine the irreducible unitary representations of t…
On the irreducibility of the commuting variety of a symmetric pair associated to a parabolic subalgebra with abelian unipotent radical
Herve Sabourin, Rupert W. T. Yu
In this paper, we study the commuting variety of symmetric pairs associated to parabolic subalgebras with abelian unipotent radical in a simple complex Lie algebra. By using the ``…
