Research

The research expertise of Motohico Mulase lies in the interplay of many areas of mathematics, such as algebraic geometry of moduli spaces or Riemann surfaces and vector bundles, nonlinear integrable systems such as KP and KdV equations, Gromov-Witten theory, and topological string theory. His research accomplishments include a solution to the Schottky problem (a characterization of Jacobian varieties) in terms of KP equations [1], establishing the solvability of soliton equations [2], a proof of the Bouchard-Marino conjecture on Hurwitz numbers [3,4], and the discovery of the virtual Poincare polynomials of the moduli space of pointed smooth curves[5].
