In this paper, we study existence, nonexistence, and properties of solutions for some Kirchhoff–Schrödinger–Maxwell systems as (1.3). The solutions can be seen as saddle points of functionals which are unbounded both from above and from below.

Kirchhoff–Schrödinger–Maxwell方程组的存在性结果

在本文中，我们研究（1.3）的某些Kirchhoff-Schrödinger-Maxwell系统的解的存在性，不存在性和性质。这些解决方案可以看作是功能的鞍点，无论从上方还是从下方都不受限制。
