We review some of the uses of Whitham hierarchies in the context of thetheory of the prepotential in N=2 supersymmetric gauge theories. We focus onthe structure of the contact terms in the twisted topological theory, and onthe connection between Whitham hierarchies and the u-plane integrals for higherrank gauge groups, trying to put together the different approaches involved inthis connection. We also review two other uses of the Whitham hierarchies: theinterpretation of the slow times as supersymmetry breaking parameters, and thenew techniques to extract instanton corrections using the RG equations writtenin terms of theta functions.Comment: 24 pages, PTP TeX. Talk given at the workshop ``Gauge theory and integrable models" (YITP, Kyoto), January 26-29, 199
