Approximate Generalized Conditional Symmetries for the Perturbed General KdV--Burgers Equation
-
Abstract
The approximate generalized conditional symmetry (AGCS) approach we previously proposed Chin. Phys. Lett.23(2006)527 is applied to study the perturbed general KdV--Burgers (KdVB) equation. Complete classification of those perturbed general KdVB equations which admit certain types of AGCSs is obtained. Approximate solutions to the perturbed equations can be derived from the corresponding unperturbed ones.
