Abstract

Integral of a certain multivalued form over cycle Δ provides zonal spherical function of type An. This paper is devoted to quantum group analysis and verification of monodromy properties of the distinguished cycle Δ. Zonal spherical function is a particular conformal block of WAn-algebra.
