ABSTRACT

We consider a semilinear differential variational inequality P in reflexive Banach spaces, governed by a set of constraints K. We associate to P a sequence of problems {Pn} where, for each nN, Pn is a differential variational inequality governed by a set of constraints Kn and a penalty parameter ρn. We use a result in [Liu ZH, Zeng SD. Penalty method for a class of differential variational inequalities. Appl Anal. 2019;1–16. doi:10.1080/00036811.2019.1652736] to prove the unique solvability of problems {P} and {Pn}. Then, we prove that, under appropriate assumptions, the sequence of solutions to Problem Pn converges to the solution of the original problem P. The proof is based on arguments of compactness, pseudomonotonicity and Mosco convergence. We also present two relevant particular case of our convergence result, including a recent result obtained in [Liu ZH, Zeng SD. Penalty method for a class of differential variational inequalities. Appl Anal. 2019;1–16. doi:10.1080/00036811.2019.1652736], in the case Kn=V. Finally, we provide an example of initial and boundary value problem for which our abstract results can be applied.
