摘要

在本文中，我们考虑了一类在无穷远处存在共振的渐近线性阻尼振动问题。与现有结果相比，在这种共振条件下，问题对应的函数可能不满足紧凑性条件。通过结合惩罚函数技术、莫尔斯理论和两个临界点定理，我们得到了非微观周期解的存在性和多重性。

Periodic solutions for a class of asymptotically linear damped vibration problems with resonance at infinity

In this paper, we consider a class of asymptotically linear damped vibration problems with resonance at infinity. Compared with the existing results, under this resonance condition the functional corresponding to the problem may not satisfy the compactness condition. By combining the penalized functional technique, Morse theory and two critical point theorems, we obtain the existence and multiplicity of nontrivial periodic solutions.

期刊介绍： Qualitative Theory of Dynamical Systems (QTDS) publishes high-quality peer-reviewed research articles on the theory and applications of discrete and continuous dynamical systems. The journal addresses mathematicians as well as engineers, physicists, and other scientists who use dynamical systems as valuable research tools. The journal is not interested in numerical results, except if these illustrate theoretical results previously proved.
