Variable-Coefficient Exact Solutions for Nonlinear Differential Equations by a New Bernoulli Equation-Based Subequation Method

الملخص EN

A new Bernoulli equation-based subequation method is proposed to establish variable-coefficient exact solutions fornonlinear differential equations.

For illustrating the validity of this method, we apply it to the asymmetric (2 + 1)-dimensional NNVsystem and the Kaup-Kupershmidt equation.

As a result, some new exact solutions with variable functions coefficients for them are successfully obtained.
