  • Two nontrivial critical points for nonsmooth functionals via local linking and applications
    Kandilakis, Dimitrios ; Kourogenis, Nikolaos C. ; Papageorgiou, Nikolaos, 1958-
    In this paper, we extend to nonsmooth locally Lipschitz functionals the multiplicity result of H. R. Brezis and L. Nirenberg [Comm. Pure Appl. Math. 44 (1991), no. 8-9, 939-963] based on a local ... linking condition. Our approach is based on the nonsmooth critical point theory for locally Lipschitz functions which uses the Clarke subdifferential. We present two applications. The first concerns periodic systems driven by the ordinary vector ▫$p$▫-Laplacian. The second concerns elliptic equations at resonance driven by the partial ▫$p$▫-Laplacian with Dirichlet boundary condition. In both cases the potential function is nonsmooth and locally Lipschitz.
