A class of (2+1) dimentional disturbed time-delay breaking solitary wave equation is studied. Firstly, the corresponding non-delay breaking equation is considered. The exact solitary wave solution is obtained by using the mapping method with undetermined coefficients. Then, the travelling asymptotic solution of disturbed breaking solitary wave equation is found by using the homotopic mapping and perturbed approximate method.
