Darboux transformation and explicit solutions for some (2+12+1)-dimensional equations

Three systems of (2+1)(2+1)-dimensional soliton equations and their decompositions into the (1+1)(1+1)-dimensional soliton equations are proposed. These equations include KPI, CKP, MKPI. With the help of Darboux transformation of (1+1)(1+1)-dimensional equations, we get the explicit solutions of the (2+1)(2+1)-dimensional equations.
