Non-linear second-order periodic systems with non-smooth potential
Evgenia H Papageorgiou, Nikolaos S Papageorgiou
In this paper we study second order non-linear periodic systems driven by the ordinary vector -Laplacian with a non-smooth, locally Lipschitz potential function. Our approach is…

Nonlinear second-order multivalued boundary value problems
Leszek Gasinski, Nikolaos S. Papageorgiou
In this paper we study nonlinear second-order differential inclusions involving the ordinary vector -Laplacian, a multivalued maximal monotone operator and nonlinear multivalued…
