A Diversity Of Localized Structures In A (2 + 1 )-dimensional Kdv Equation

摘要

The singular manifold method is used to solve a (2 + 1 )-dimensional KdV equation. An exact solution containing two arbitrary functions is then obtained. A diversity of localized structures, such as generalized dromions and solitoffs, is exposed by making full use of these arbitrary functions. These localized structures are illustrated by graphs.
