A class of functionals possessing multiple global minima [PDF]
We get a new multiplicity result for gradient systems. Here is a very particular corollary: Let Ω ⊂ Rn (n ≥ 2) be a smooth bounded domain and let Φ : R2 → R be a C1 function, with Φ(0, 0) = 0, such that... Mathematics Subject Classification (2010): 35J47,

Nonautonomous fractional Hamiltonian system with critical exponential growth [PDF]
International audienceIn this paper, we study the following nonlocal nonautonomous Hamiltonian system on whole R (−∆) 1 2 u + u = Q(x)g(v) in R, (−∆) 1 2 v + v = P (x)f (u) in R, where (−∆) 1 2 is the square root Laplacian operator.

Fourth order elliptic system with dirichlet boundary condition [PDF]
We investigate the multiplicity of the solutions of the fourth order elliptic system with Dirichlet boundary condition. We get two theorems. One theorem is that the fourth order elliptic system has at least two nontrivial solutions when λ k < c &

Stability of solitary-wave solutions of coupled NLS equations with power-type nonlinearities
This paper proves existence and stability of solitary-wave solutions of a system of 2-coupled nonlinear Schrödinger equations with power-type nonlinearities arising in several models of modern physics. The existence of vector solitary-wave solutions (i.e.

Multiple positive solutions for quasilinear elliptic problems with sign‐changing nonlinearities
Using variational arguments, we prove some nonexistence and multiplicity results for positive solutions of a system of p‐Laplace equations of gradient form. Then we study a p‐Laplace‐type problem with nonlinear boundary conditions.

A note on the variational structure of an elliptic system involving critical Sobolev exponent
We consider an elliptic system involving critical growth conditions. We develop a technique of variational methods for elliptic systems. Using the well‐known results of maximum principle for systems developed by Fleckinger et al. (1995), we can find positive solutions.

Quasilinear elliptic systems of resonant type and nonlinear eigenvalue problems
This work is devoted to the study of a quasilinear elliptic system of resonant type. We prove the existence of infinitely many solutions of a related nonlinear eigenvalue problem. Applying an abstract minimax theorem, we obtain a solution of the quasilinear system −Δpu = Fu(x, u, v), − Δqv = F v(x, u, v), under conditions involving the first and the ...
