Abstract

In this paper, we deal with the existence and multiplicity of component-wise nontrivial critical points (i.e., whose components are both nonzero) for an abstract C1 -functional J defined in X×X with X being a reflexive Banach space. Applying the Nehari manifold method and the minimization method along with the geometric properties of the constructed functions, we investigate the existence and multiplicity of component-wise nontrivial critical points of J. As applications, we prove the existence and multiplicity of component-wise nontrivial solutions for the second-order and fourth-order elliptic systems. Our theoretical results improve and extend the relevant results in the existing literature.
