Abstract:We discuss a parametric eigenvalue problem, where the differential operator is of (p, 2)-Laplacian type. We show that, when p 2, the spectrum of the operator is a half line, with the end point formulated in terms of the parameter and the principal eigenvalue of the Laplacian with zero Dirichlet boundary conditions. Two cases are considered corresponding to p > 2 and p < 2, and the methods that are applied are variational. In the former case, the direct method is applied, whereas in the latter case, the fiberin… Show more

We study the ground state solutions for the following p&q-Laplacian equationwhere 𝜆 > 0 is a parameter large enough, Δ r u = div(|∇u| r−2 ∇u) with r ∈ {p, q} denotes the r-Laplacian operator, 1 < p < q < N and q * = Nq∕(N − q). Under some assumptions for the periodic potential V, weight function K and nonlinearity 𝑓 without the Ambrosetti-Rabinowitz condition, we show the above equation has a ground state solution.
