Grammian solutions and Pfaffianization of the non-isospectral modified Kadomtsev–Petviashvili equation

Abstract The Grammian determinant solutions of the non-isospectral modified Kadomtsev–Petviashvili (mKP) equation are presented. Moreover, a new non-isospectral coupled system is constructed by using the Pfaffianization procedure. Furthermore, Gramm-type Pfaffian solutions of the non-isospectral coupled system are obtained.
