Abstract:

In this talk I will describe relations between three enumerative geometry tau-functions: the Kontsevich--Witten, Hurwitz and Hodge tau-functions. The relations allow us to describe the tau-functions in terms of matrix integrals, Virasoro constraints and Kac--Schwarz operators. All constructed operators belong to the algebra (or group) of symmetries of the KP hierarchy.
