Multi-peak solutions to Kirchhoff equations in \(\mathbb{R}^3\) with general nonlinearity. (English) Zbl 1398.35058

Summary: We are concerned with the existence of multi-peak solutions to Kirchhoff equation \[ -\Big(\epsilon^2 a + \epsilon b \mathop{\int}\limits_{\mathbb{R}^3} | \nabla u |^2 d x\Big) \Delta u + V(x) u = f(u),\quad x \in \mathbb{R}^3,\eqno{(0.1)} \] where \(\epsilon > 0\) is a small parameter, \(a\), \(b > 0\) are constants. Under general conditions of \(f\), we construct a family positive solutions \(u_\epsilon \in H^1(\mathbb{R}^3)\) which concentrates around the isolated components of positive local minima of \(V\) as \(\epsilon \rightarrow 0^+\). Our result generalize the previous results on single peak solutions to multi-peak solutions.
