Sign-changing solutions for a nonlinear degenerate elliptic system
Keywords:
degenerate elliptic system, truncation method, sign-changing solutions, method of invariant sets of descending flowAbstract
In this article, we study the multiplicity of weak solutions to the non-linear degenerate elliptic system. The existence of sign-changing solutions is proved by the truncation method and the invariant sets of descending flow method.
