| Abstract: | Basing on the direct method developed by Clarkson and Kruskal, the nonisospectral BKP equation can be reduced to three types of (1+1)-dimensional variable coefficients partial differential equations (PDEs).Furthermore, on the basis of the idea of the symmetry group direct method by Lou et al., three types of reduction PDEs are all reduced tothe related constant coefficients PDEs by some transformations. |
