Subcritical Perturbations of Resonant Linear Problems with Sign-changing Potential
نویسنده
چکیده
We establish existence and multiplicity theorems for a Dirichlet boundary-value problem at resonance. This problem is a nonlinear subcritical perturbation of a linear eigenvalue problem studied by Cuesta, and includes a sign-changing potential. We obtain solutions using the Mountain Pass lemma and the Saddle Point theorem. Our paper extends some recent results of Gonçalves, Miyagaki, and Ma.

Positive and Sign-changing Clusters around Saddle Points of the Potential for Nonlinear Elliptic Problems
We study the existence and asymptotic behavior of positive and sign-changing multipeak solutions for the equation −ε∆v + V (x)v = f(v) in R , where ε is a small positive parameter, f is a superlinear, subcritical and odd nonlinearity, V is a uniformly positive potential. No symmetry on V is assumed. It is known ([19]) that this equation has positive multipeak solutions with all peaks approachin...
متن کاملMountain pass and linking type sign-changing solutions for nonlinear problems involving the fractional Laplacian
where ⊂Rn (n≥ 2) is a bounded smooth domain, s ∈ (0, 1), (– )s denotes the fractional Laplacian, λ is a real parameter, the nonlinear term f satisfies superlinear and subcritical growth conditions at zero and at infinity. When λ≤ 0, we prove the existence of a positive solution, a negative solution and a sign-changing solution by combing minimax method with invariant sets of descending flow. Wh...
متن کاملElliptic equations in R with one-sided exponential growth
We consider elliptic equations in bounded domains Ω ⊂ R with nonlinearities which have exponential growth at +∞ (subcritical and critical growth respectively) and linear growth λ at −∞, with λ > λ1, the first eigenvalue of the Laplacian. We prove that such equations have at least two solutions for certain forcing terms; one solution is negative, the other one is sign-changing. Some critical gro...
متن کاملSpatial growth of fundamental solutions for certain perturbations of the harmonic oscillator
We consider the fundamental solution for the Cauchy problem for perturbations of the harmonic oscillator by time dependent potentials, which grow at spatial infinity slower than quadratic, but faster than linear functions, and whose Hessian matrices have a fixed sign. We prove that the fundamental solution at resonant times grows indefinitely at spatial infinity with the algebraic growth rate, ...
متن کاملSolitary Waves and Dynamics for Subcritical Perturbations of Energy Critical NLS
We consider a perturbed energy critical focusing Nonlinear Schrödinger Equation in three dimensions. We construct solitary wave solutions for focusing subcritical perturbations as well as defocusing supercritical perturbations. The construction relies on the resolvent expansion, which is singular due to the presence of a resonance. Specializing to pure power focusing subcritical perturbations w...
