-gradations of Lie algebras and infinitesimal generators.
In this article, we prove a generalisation of Bochner-Godement theorem. Our result deals with Olshanski spherical pairs defined as inductive limits of increasing sequences of Gelfand pairs . By using the integral representation theory of G. Choquet on convex cones, we establish a Bochner type representation of any element of the set of -biinvariant continuous functions of positive type on .
In this note, we generalize the results in our previous paper on the Casimir operator and Berezin transform, by showing the -continuity of a generalized Berezin transform associated with a branching problem for a class of unitary representations defined by invariant elliptic operators; we also show, that under suitable general conditions, this generalized Berezin transform is -continuous for
We show that a Poisson Lie group (G,π) is coboundary if and only if the natural action of G×G on M=G is a Poisson action for an appropriate Poisson structure on M (the structure turns out to be the well known ). We analyze the same condition in the context of Hopf algebras. A quantum analogue of the structure on SU(N) is described in terms of generators and relations as an example.
