High energy solutions of systems of Kirchhoff-type equations on RNRN

The main purpose of this paper is to unify and improve Theorems 3.1–3.3 in Wu (2012) [8] as well as some results in other literature such as Theorems 1–4 in Wu (2011) [9]. We present a new proof technique to conclude the existence of high energy solutions for the Kirchhoff-type system under some assumptions that are weaker than those in Wu (2012) [8].
