New families of exact solutions to the integrable dispersive long wave equations in (2+1)-dimensional spaces

The integrable dispersive long wave equations, especially the higher dimensional ones, are of current interest in both physics and mathematics. Obtained in this paper, via a symbolic-computation-based method, are new families of exact solutions to the (2 + 1)-dimensional integrable dispersive long wave equations. Sample solutions from those families are presented. Solitary waves are merely a special case in one family.
