摘要

For the Davey-Stewartson system,the exact dark solitary wave solutions,solitary wave solutions,kink wave solution and periodic wave solutions are studied.To guarantee the existence of the above solutions,all parameter conditions are determined.The persistence of dark solitary wave solutions to the perturbed Davey-Stewartson system is proved.
