    Existence and multiplicity of solutions for certain nonlinear elliptic problems
    (Université Echahid Cheikh Larbi-Tebessi -Tébessa, 2023) Fareh, Souraya
    The problem addressed in this thesis concerns the study of some nonlinear elliptic problems. Our approach is based on variational methods. First, we studied a critical Schrödinger- Kirchhoff type system involving the fractional p-Laplacian operator with Dirichlet boundary conditions, where we proved the existence of two weak solutions by using the Nehari manifold and the fibering method. Second, we considered a class of p(x)-Laplacian problems. By applying the mountain pass theorem and fountain theorem, respectively, the existence and multiplicity of solutions were obtained.
