Abstract: Integrable systems appear in geometry and physics as nonlinear differential equations with many symmetries. Using a particular example of interest in mirror symmetry and quantum field theory (the "tt*-Toda equation"), I will compare several methods for solving such equations: nonlinear p.d.e. theory, Riemann-Hilbert theory, loop group theory, and bundle methods. This is joint work with Alexander Its and Chang-Shou Lin.
