Kontsevich quantization and invariant distributions on Lie groups
Martin Andler, Alexander Dvorsky, Siddhartha Sahi
We study Kontsevich's deformation quantization for the dual of a finite-dimensional real Lie algebra (or superalgebra) g. In this case the Kontsevich star-product defines a new con…

Tensor products of singular representations and an extension of the theta-correspondence
Alexander Dvorsky, Siddhartha Sahi
In this paper we consider the problem of decomposing tensor products of certain singular unitary representations of a semisimple Lie group G. Using explicit models for these repres…
