Tau functions of the discrete modified KP hierarchy

Tau functions of the discrete modified KP hierarchy

In this paper, we prove the existence of tau functions of the discrete modified Kadomtsev-Petviashvili (KP) hierarchy. Meanwhile, the Fay identity with its difference form, the squared eigenfunction potentials, and the symmetry flows acting on tau functions are obtained.
