Abstract With the aid of the three-critical-point theorem due to Brezis and Nirenberg (see Brezis and Nirenberg in Commun. Pure Appl. Math. 44:939–963, 1991), two existence results of at least two nontrivial solutions for a class of nonlocal Kirchh

Abstract The existence of weak solutions for a class of ( p , q ) $(p,q)$ -Laplacian systems is obtained by using a new linking theorem on the product space W 0 1 , p ( Ω ) × W 0 1 , q ( Ω ) $W^{1,p}_{0}(\Omega)\times W^{1,q}_{0}(\Omega)$ .

Abstract Multiple solutions for a class of superquadratic elliptic systems near resonance with high eigenvalues are obtained by using the nabla theorem due to Marino and Saccon in (Topol. Methods Nonlinear Anal. 17:213-237, 2001) and the linking theo

We show the existence of weak solutions for a class of (p,q)-Laplacian elliptic systems at resonance, under certain Landesman-Lazer-type conditions by using critical point theorem.

In this paper, we first study the existence of ground state solutions for the following Schrödinger systems { − ∆ u + V ∞ u = G u ( u , v ) , x ∈ R N , − ∆ v + V ∞ v = G v ( u , v ) , x ∈ R N , u , v > 0 , u , v ∈ H 1 ( R N ) , whe

We are interested in the existence of positive and sign-changing solutions for a fractional Kirchhoff equation. Under some mild conditions on the potentials $ V $ and $ h $, using variational methods, we prove the existence of positive ground state s
