ABSTRACT
We consider a semilinear differential variational inequality in reflexive Banach spaces, governed by a set of constraints K. We associate to
a sequence of problems
where, for each
,
is a differential variational inequality governed by a set of constraints
and a penalty parameter
. 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
and
. Then, we prove that, under appropriate assumptions, the sequence of solutions to Problem
converges to the solution of the original problem
. 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
. Finally, we provide an example of initial and boundary value problem for which our abstract results can be applied.
