在本文中,我们考虑以下薛定谔方程:其中 V(x) 和 g(x,u) 相对于 x 是周期性的,并且 0 是频谱 σ(−Δ+V) 的边界点。用一般的超二次条件代替经典的 Ambrosetti-Rabinowitz 对 g(x,u) 的超线性假设,我们能够获得非平凡解的存在性。
In this paper we consider the following Schrödinger equation: where V(x) and g(x,u) are periodic with respect to x and 0 is a boundary point of the spectrum σ(−Δ+V). Replacing the classical Ambrosetti–Rabinowitz superlinear assumption on g(x,u) by a general super-quadratic condition, we are able to obtain the existence of nontrivial solutions.
