THE OPTIMIZATION OF EIGENVALUE PROBLEMS INVOLVING THE p-LAPLACIAN
Given a bounded domain Ω ⊂ R and numbers p > 1, α ≥ 0, A ∈ [0, |Ω|], consider the following optimization problem: find a subset D ⊂ Ω, of measure A, for which the first eigenvalue of the operator −∆p + αχD φp with the Dirichlet boundary condition is as small as possible. We prove the existence of optimal solutions and study their qualitative properties. We also obtain the radial symmetry of opt...
متن کاملOptimization of the First Eigenvalue in Problems Involving the Bi–laplacian
This paper concerns minimization and maximization of the first eigenvalue in problems involving the bi-Laplacian under Dirichlet boundary conditions. Physically, in case of N = 2 , our equation models the vibration of a non homogeneous plate Ω which is clamped along the boundary. Given several materials (with different densities) of total extension |Ω| , we investigate the location of these mat...
متن کاملMULTIPLICITY RESULTS FOR p-SUBLINEAR p-LAPLACIAN PROBLEMS INVOLVING INDEFINITE EIGENVALUE PROBLEMS VIA MORSE THEORY
We establish some multiplicity results for a class of p-sublinear pLaplacian problems involving indefinite eigenvalue problems using Morse theory.
متن کاملSTEKLOV PROBLEMS INVOLVING THE p(x)-LAPLACIAN
Under suitable assumptions on the potential of the nonlinearity, we study the existence and multiplicity of solutions for a Steklov problem involving the p(x)-Laplacian. Our approach is based on variational methods.
متن کاملEIGENVALUE PROBLEMS WITH p-LAPLACIAN OPERATORS
In this article, we study eigenvalue problems with the p-Laplacian operator: −(|y′|p−2y′)′ = (p− 1)(λρ(x)− q(x))|y|p−2y on (0, πp), where p > 1 and πp ≡ 2π/(p sin(π/p)). We show that if ρ ≡ 1 and q is singlewell with transition point a = πp/2, then the second Neumann eigenvalue is greater than or equal to the first Dirichlet eigenvalue; the equality holds if and only if q is constant. The same ...
