Simple Lie algebras, periods, and topological ODEs
We study the topological ODE associated with each simple Lie algebra. For a simply-laced simple Lie algebra, we discuss the conjectural relationship between the fundamental series (which characterize solutions to the topological ODE) and periods (which characterize solutions to the associated Gauss-Manin connection). The seminar is based on a series of joint work with Marco Bertola, Boris Dubrovin and Don Zagier.
