Title: Existence results and applications for general variational-hemivariational inequalities on unbounded domains Authors: Ildiko-Ilona Mezei (Univ. of Babes-Bolyai, Romania) Lia Saplacan (Petru Rares High School, Romania) Abstract: In this paper we give an existence result for a class of variational-hemivariational inequality on unbounded domain using the mountain pass theorem and the principle of symmetric criticality for Motreanu-Panagiotopoulos type functionals. Next, we give two applications of the obtained result. Submitted February 2, 2009. Published April 02, 2009. Math Subject Classifications: 49J40, 35J35, 35J60.
