Exact propagating dromion-like localized wave solutions of a generalised (2+1) dimensional Davey Stewartson equations
Document info: Pages 22, Figures 3.
The capacity of double-Exponential(Exp) function method as an alternative approach to obtain the analytic solutions of higher dimensional coupled nonlinear partial differential equations in Engineering mathematics has been revealed. We employ the double-Exp method aided with symbolic computation to construct dromion-like localized solutions for a (2+1)-dimensional generalized Davey-Stewartson(2DGDS) system of equations governing the dynamics of weakly nonlinear modulation of a lattice wave packet in a multi-dimensional lattice. The multidromion-like solutions obtained by the present approach are more general than those obtained earlier.
