High energy solutions of general Kirchhoff type equations without the Ambrosetti-Rabinowitz type condition

Abstract

Abstract In this article, we study the following general Kirchhoff type equation: − M ∫ R 3 ∣ ∇ u ∣ 2 d x Δ u + u = a ( x ) f ( u ) in R 3 , -M\left(\mathop{\int }\limits_{{{\mathbb{R}}}^{3}}| \nabla u{| }^{2}{\rm{d}}x\right)\Delta u+u=a\left(x)f\left(u)\hspace{1em}{\rm{in}}\hspace{0.33em}{{\mathbb{R}}}^{3}, where inf R + M > 0 {\inf }_{{{\mathbb{R}}}^{+}}M\gt 0 and f f is a superlinear subcritical term. By using the Pohozǎev manifold, we obtain the existence of high energy solutions of the aforementioned equation without the well-known Ambrosetti-Rabinowitz type condition.
