在本文中,我们应用 Ambrosetti-Rabinowitz 和 Ambrosetti-Coti Zelati 著名的山口引理的变体以及 Palais-Smale-Cerami 的 (PSC)c 型条件来研究具有弱力型势的对称奇异二阶哈密顿保守系统的具有指定能量的新周期解的存在性。
In this paper, we apply a variant of the famous Mountain Pass Lemmas of Ambrosetti-Rabinowitz and Ambrosetti-Coti Zelati with (PSC)ctype condition of Palais-Smale-Cerami to study the existence of new periodic solutions with a prescribed energy for symmetrical singular second order Hamiltonian conservative systems with weak force type potentials.
