报告摘要:The notion of Frobenius manifolds was introduced by Boris Dubrovin in the early 1990s. It has played important roles in the study of Gromov-Witten theory, singularity theory, integrable systems and some other research fields of mathematical physics. In this talk, I will recall the definition and basic properties of Frobenius manifolds, explain how to associate a semisimple Frobenius manifold with a hierarchy of integrable evolutionary PDEs, and review some recent progresses in the study of properties of such integrable hierarchies, including their bihamiltonian structures and Virasoro symmetries.
