摘   要:  In this talk we will report the generalized additional symmetries of the two-Toda lattice hierarchy. The new additional symmetries are found, i.e., Beltrami algebra and Block type algebra symmetries. In order to discuss the actions of these algebras on tau-function, we restrict the two-Toda lattice hierarchy to the semi-infinite case, which is related to the two-matrix integrals. A new trace formula is derived. By using this we present the actions of the Beltrami algebra and Block type algebra on the two-matrix integral.
