A non-degeneracy theorem for positive solutions of the standard Kirchhoff model is proved in all cases except for n≥ 5 and b∫ R n|∇ Q| 2 d x= 2 (n− 4) n− 4 2/(n− 2) n− 2 2. In particular, for dimensions n≥ 5 and b∫ R n|∇ Q| 2 d x< 2 (n− 4) n− 4 2/(n− 2) n− 2 2, we show that there exist two non-degenerate positive solutions of the Kirchhoff equations, which seem to be completely different from the result of the standard Schrödinger equation. The effects of the non-local term on the positive solution set are also studied. We show that the non-local term has no effect on the structure of the positive solution set for dimensions 1≤ n≤ 3 and the effects eventually appear for dimensions n≥ 4. With the non-degeneracy property of positive solutions of the limit problem, we construct concentrated solutions of a singularly perturbed Kirchhoff problem via the well-known Lyapunov–Schmidt reduction method. For dimensions n≥ 5, the existence result of concentrated solutions is completely new and is not implied by the main result of GM Figueiredo et al. in [19], where a generalized singularly perturbed Kirchhoff problem was considered.
