In the present paper, we consider the existence of ground state sign-changing solutions for a class of Kirchhoff-type problems
equation(0.1)
where Ω⊂RN is a bounded domain with a smooth boundary ∂Ω, , a>0, b>0 and . Under some weak assumptions on f, with the aid of some new analytical skills and Non-Nehari manifold method, we prove that (0.1) possesses one ground state sign-changing solution a07970a" title="Click to view the MathML source">ub, and its energy is strictly larger than twice that of the ground state solutions of Nehari-type. Furthermore, we establish the convergence property of a07970a" title="Click to view the MathML source">ub as the parameter b↘0. Our results improve and generalize some results obtained by W. Shuai (2015) [34].
