Tilte: Riemann-Hilbert approach to the WDVV and tt* equations

Abstract: This talk first gives an introduction to the WDVV equation, its Lax pair and monodromy data. It then uses the Riemann-Hilbert method to compute explicitly the long time asymptotics of the equation in terms of the monodromy data. As an application, it outlines a systematic way to construct speical solutions of the WDVV equation. If time permitted, it also states the similar results for tt* equations.
