　　报告摘要：The talk deals with the intersection between Block algebras and several kinds of integrable hierarchies. The Block algebra is one kind of Lie algebra which contains the well-known Virasoro algebra as a subalgebra. The quantilization of Block algebra is the quantum torus algebra. The Virasoro constraint on tau functions was widely used in topological field theory and random matrix theory. The talk will introduce a method to construct the additional symmetry of integrable systems. These additional symmetries can have a nice structure of Block type Lie algebra and their generating function will lead to a nice source of symmetries which can be used to construct integrable systems with sources and constraints.
