D. Motreanu et Pd. Panagiotopoulos, ON THE EIGENVALUE PROBLEM FOR HEMIVARIATIONAL INEQUALITIES - EXISTENCE AND MULTIPLICITY OF SOLUTIONS, Journal of mathematical analysis and applications, 197(1), 1996, pp. 75-89
In this article the eigenvalue problem for hemivariational inequalitie
s is studied. First some existence results are obtained by applying a
critical point method suitable for nonconvex nonsmooth energy function
s. Further some results concerning the multiplicity of solutions are p
roved. Applications from mechanics illustrate the theory. (C) 1996 Aca
