The modified Exp-function method and its applications to the generalized K(n,n) and BBM equations with variable coefficients

In this article, the modified exp-function method is used to construct many exact solutions to the nonlinear generalized K(n,n) and BBM equations with variable coefficients. Under different parameter conditions, explicit formulas for some new exact solutions are successfully obtained. The proposed solutions are found to be important for the explanation of some practical physical problems.
