| contents | In this paper, we are concerned with the sign-changing solutions of variational inequality problems. In order to give the existence results of the sign-changing solutions for variational inequality problems, we first construct a suitable penalty problem related to the variational inequality, and prove the existence of a sign-changing solution for this penalty problem using the invariant set of descending flow method. Secondly, we perform a series of estimates on the sign-changing solution sequence of the penalty problem, and prove that the limit of convergence of the sign-changing solution sequence is the sign-changing solution of the original variational inequality problem. Variational inequality problems have extensive and important applications. In this paper, we used penalty method and the method of invariant set of descending flow to obtain the existence results for solutions of a variational inequality. In particular, we obtain the existence results for sign-changing solutions of variational inequalities for the first time based on the method of invariant set of descending flow. |
