Generalized Wronskian and Grammian Solutions to a Isospectral B-type Kadomtsev-Petviashvili equation

Generally speaking, the BKP hierarchy which only has Pfaffian solutions. In this paper, based on Grammian and Wronskian derivative formulae, generalized determinant solutions are obtained for isospectral equation (the second member hierarchy) in Hirota bilinear form. Especially, with help of properties computing Young diagram, we have first applied diagram proved proposition paper. Moreover, by considering different combinations entries Wronskian, obtain various types
