【Abstract】 By using the Hirota’s bilinear form and generalized three-wave approach, we construct multiple periodic-soliton solutions of(3+1)-dimensional potential-YTSF equation. Some entirely new periodic-soliton solutions are presented including periodic cross-kink wave, periodic two-solitary wave and breather type of two-solitary wave solutions. With the aid of symbolic computation, propagation characteristics and interactions of breathers and solitons are shown with some figures.更多还原
