Abstract

The prepotential , defining the low-energy effective action of the SUSY Yang-Mills theories, satisfies an enlarged set of the WDVV-like equations for any triple , where matrix is equal to . The same equations are actually true for generic topological theories. In contrast to the conventional formulation, when is restricted to , in the proposed system there is no distinguished ``first'' time-variable, and indices can be raised with the help of any ``metric'' , not obligatory flat. All the equations (for all ) are true simultaneously. This result provides a new parallel between the Seiberg-Witten theory of low-energy gauge models in and topological theories.
