*讲座内容简介：
In the talk, we will show you some results on nonlocal symmetries and their applications. Sato theory, developed by Mikio Sato and his school in Kyoto, contains many interesting mathematical structures and in particular provides the construction of hierarchies of soliton equations, written in terms of tau-functions depending on infinite number of independent variables. In this talk, the tau function and additional symmetries of q-mKP hierarchy are introduced.
