The $\tau$-function of the universal Whitham hierarchy, matrix models and topological field theories
Abstract
The universal Witham hierarchy is considered from the point of view of topological field theories. The $\tau$-function for this hierarchy is defined. It is proved that the algebraic orbits of Whitham hierarchy can be identified with various topological matter models coupled with topological gravity.
