New variable separation excitations,rectangle-like solitons and fractal solitons in the Boiti-Leon-Pempinelli system
Boiti-Leon-Pempinelli系统的新变量分离解及其方形孤子和分形孤子

Using an extended Riccati mapping approach,we obtain a new type of varable separation solutions for the (2+1)-dimensional Boiti-Leon-Pempinelli system.Based on the derived solutions,two new kinds of soliton excitations,i.e.rectangle-like soliton and fractal soliton are constructed in this paper.
