摘要：I will introduce some of the differential equations which arise in quantum cohomology: the quantum differential equations, the WDVV equations, and the tt*-equations. These differential equations are motivated by the theory of Gromov-Witten invariants, but they have relations with various topics in differential, algebraic, and symplectic geometry. They are also "integrable systems", in the sense that they have many algebraic symmetries. In some cases at least, these symmetries can be used to solve the equations.
