Nontrivial solutions for Klein–Gordon–Maxwell systems with sign-changing potentials
نویسندگان
چکیده
Abstract This paper is concerned with the nonlinear Klein–Gordon–Maxwell systems. Unlike all known results in literature, Schrödinger operator $-\Delta +V$ − Δ + V allowed to be indefinite and weaker superlinear conditions are imposed instead of common 4-superlinear on f . By combining a local linking argument Morse theory, we obtain that system admits nontrivial solution.

Multiplicity of Positive Solutions of laplacian systems with sign-changing weight functions
In this paper, we study the multiplicity of positive solutions for the Laplacian systems with sign-changing weight functions. Using the decomposition of the Nehari manifold, we prove that an elliptic system has at least two positive solutions.
متن کاملExistence of Nontrivial Solutions for Singular Quasilinear Equations with Sign Changing Nonlinearity
By an application of Bonanno’s three critical point theorem, we establish the existence of a nontrivial solution to the problem −∆pu = μ g(x)|u|p−2u |x|p + λa(x)f(u) in Ω, u = 0 on ∂Ω, under some restrictions on g, a and f for certain positive values of μ and λ.
متن کاملInfinitely many solutions for a bi-nonlocal equation with sign-changing weight functions
In this paper, we investigate the existence of infinitely many solutions for a bi-nonlocal equation with sign-changing weight functions. We use some natural constraints and the Ljusternik-Schnirelman critical point theory on C1-manifolds, to prove our main results.
متن کاملEXISTENCE OF POSITIVE AND SIGN-CHANGING SOLUTIONS FOR p-LAPLACE EQUATIONS WITH POTENTIALS IN R
We study the perturbed equation −ε div(|∇u|p−2∇u) + V (x)|u|p−2u = h(x, u) + K(x)|u| −2u, x ∈ R u(x)→ 0 as |x| → ∞ . where 2 ≤ p < N , p∗ = pN N−p , p < q < p ∗. Under proper conditions on V (x) and h(x, u), we obtain the existence and multiplicity of solutions. We also study the existence of solutions which change sign.
متن کاملExistence and multiplicity of nontrivial solutions for $p$-Laplacian system with nonlinearities of concave-convex type and sign-changing weight functions
This paper is concerned with the existence of multiple positive solutions for a quasilinear elliptic system involving concave-convex nonlinearities and sign-changing weight functions. With the help of the Nehari manifold and Palais-Smale condition, we prove that the system has at least two nontrivial positive solutions, when the pair of parameters $(lambda,mu)$ belongs to a c...
