Abstract
The integral of a certain multivalued form over a cycle A provides the zonal spherical function of type An. This paper is devoted to a quantum group analysis and verification of monodromy properties of the distinguished cycle Δ. The zonal spherical function in the case of the root system of type An is a particular conformal block of the WA n-algebra.
