Abstract : The generalizations are constructed systematically with each of the lower dimensional cases explored appropriately. The Hirota bilinear forms of the constructed generalized partial differential equations are then derived utilizing key bilinear form identities. Along with the bilinear form representations, one-soliton based dispersion relations and two-soliton interaction coefficients are derived systematically. Anisotropic generalizations of the CBS equation and the variable coefficient KP equation are also deliberated which collectively provide a unified framework applicable across numerous disciplines of nonlinear sciences.
