Integrability properties of Hurwitz partition functions. II. Multiplication of cut-and-join operators and WDVV equations

A bstract Correlators in topological theories are given by the values of a linear form on the products of operators from a commutative associative algebra (CAA). As a corollary, partition functions of topological theory always satisfy the generalized WDVV equations of [42]. We consider the Hurwitz p...
