报告题目：Lump solutions to dispersive wave equations
Abstract: I would like to talk about lump solutions to dispersive wave equations, both linear and nonlinear. Within the Hirota bilinear formulation, a general characterization on the existence of lump solutions in general dimensions will be discussed, and illustrative examples of lump solutions to dispersive wave equations in (2+1)- and (3+1)-dimensions will be presented through Maple symbolic computations. A few open questions will be addressed at the end of the talk.
