Mathematik-Bericht 2010/2 The heat semigroup in the com- pact Heckman-Opdam setting and the Segal-Bargmann transform

چکیده
In the first part of this paper, we study the heat equation and the heat kernel associated with the Heckman-Opdam Laplacian in the compact, Weyl-group invariant setting. In particular, this Laplacian gives rise to a Feller-Markov semigroup on a fundamental alcove of the affine Weyl group. The second part of the paper is devoted to the Segal-Bargmann transform in our context. A Hilbert space of holomorphic functions is defined such that the L-heat transform becomes a unitary isomorphism.

Mathematik-Bericht 2009/8 Convolution algebras for Heckman- Opdam polynomials derived from compact Grassmannians
We study convolution algebras associated with HeckmanOpdam polynomials. For root systems of type BC we derive three continuous classes of positive convolution algebras (hypergroups) by interpolating the double coset convolution structures of compact Grassmannians U/K with fixed rank over the real, complex or quaternionic numbers. These convolution algebras are linked to explicit positive produc...
متن کاملThe Segal–bargmann Transform for Noncompact Symmetric Spaces of the Complex Type
We consider the generalized Segal–Bargmann transform, defined in terms of the heat operator, for a noncompact symmetric space of the complex type. For radial functions, we show that the Segal–Bargmann transform is a unitary map onto a certain L space of meromorphic functions. For general functions, we give an inversion formula for the Segal–Bargmann transform, involving integration against an “...

Let K be a connected compact semisimple Lie group and KC its complexification. The generalized Segal–Bargmann space for KC, is a space of square-integrable holomorphic functions on KC, with respect to a K-invariant heat kernel measure. This space is connected to the “Schrödinger” Hilbert space L(K) by a unitary map, the generalized Segal–Bargmann transform. This paper considers certain natural ...

Let μ (q) p be the q-deformed Poisson measure in the sense of SaitohYoshida [24] and νp be the measure given by Equation (3.6). In this short paper, we introduce the q-deformed analogue of the Segal-Bargmann transform associated with μ (q) p . We prove that our Segal-Bargmann transform is a unitary map of L(μ (q) p ) onto the q-deformed Hardy spaceH (νq). Moreover, we give the Segal-Bargmann re...
