Areas of Expertise: Partial differential equations and
inverse scattering theory
Research Summary:
Professor Zhou studies the 1-D, 2-D inverse scattering
theory, using the method of
Riemann-Hilbert problems. His current research is
concentrated in a nonlinear type of microlocal analysis on
Riemann-Hilbert problems. Subjects of main interest are integrable
and near intergrable PDE, integrable statistical models, orthogonal
polynomials and random matrices, monodromy groups and Painleve equations
with applications in physics and algebraic geometry.
A number of classical and new problems in analysis, numerical analysis, and physics
have been solved by zhou or jointly by zhou and his collaborators.
