A differential-difference Kadomtsev-Petviashvili family possesses a common Kac-Moody-Virasoro symmetry algebra

Starting from the Kac-Moody-Virasoro symmetry algebra of the differential-difference Kadomtsev-Petviashvili equation, a differential-difference Kadomtsev-Petviashvili family is constructed and the corresponding invariant solutions are obtained.
