HARISH-CHANDRA DECOMPOSITION FOR ZONAL SPHERICAL FUNCTION OF TYPE An A. Kazarnovski-Krol
نویسنده
چکیده
Heckman-Opdam system of differential equations is holonomic , with regular singularities and has locally |W |-dimensional space of solutions ( cf. corollary 3.9 of [12]), where |W | is the cardinality of the Weyl group W . The system is a generalization of radial parts of Laplace-Casimir operators on symmetric Riemannian spaces of nonpositive curvature and is isomorphic to Calogero-Sutherland model in the integrable systems.

CYCLE FOR INTEGRATION FOR ZONAL SPHERICAL FUNCTION OF TYPE An A.Kazarnovski-Krol
Integral of a certain multivalued form over cycle ∆ provides zonal spherical function of type An. This paper is devoted to quantum group analysis and verification of monodromy properties of the distinguished cycle ∆. Zonal spherical function is a particular conformal block of WAn-algebra 0.0 Notations. α1, α2, . . . , αn simple roots of root system of type An R+ set of positive roots R root sys...
متن کاملInverse Harish - Chandra transform and difference operators
In the paper we calculate the images of the operators of multiplication by Laurent polynomials with respect to the Harish-Chandra transform and its non-symmetric generalization due to Opdam. It readily leads to a new simple proof of the Harish-Chandra inversion theorem in the zonal case (see [HC,He1]) and the corresponding theorem from [O1]. We assume that k > 0 and restrict ourselves to compac...
متن کاملInvariant Differential Operators for Quantum Symmetric Spaces, II
The two papers in this series analyze quantum invariant differential operators for quantum symmetric spaces in the maximally split case. In this paper, we complete the proof of a quantum version of Harish-Chandra’s theorem: There is a Harish-Chandra map which induces an isomorphism between the ring of quantum invariant differential operators and a ring of Laurent polynomial invariants with resp...
متن کاملSpherical Transform and Jacobi Polynomials on Root Systems of Type Bc
Let R be a root system of type BC in a = Rr of general positive multiplicity. We introduce certain canonical weight function on Rr which in the case of symmetric domains corresponds to the integral kernel of the Berezin transform. We compute its spherical transform and prove certain Bernstein-Sato type formula. This generalizes earlier work of Unterberger-Upmeier, van Dijk-Pevsner, Neretin and ...
متن کاملSpherical Functions and Spherical Laplace Transform on Ordered Symmetric Space
Let G=H be a semisimple globally hyperbolic symmetric space and let ' be a H-spherical function on G=H. We derive an expansion formula for ' similar to the Harish-Chandra formula for spherical functions on a Riemannian symmetric space. We use this result to analytically continuate the spherical functions in the parameters. A functional equation for ' is derived and then used to invert the spher...
