Constrained discrete KP hierarchy: The constraint on the tau functions and gauge transformations

We investigate two topics of the constrained discrete KP hierarchy: the constraint on the tau functions and gauge transformations. For the constrained dKP hierarchy, the constraint on the Lax operator is shown to be equivalent to a constraint on the tau function, which provides another description o...
