本文主要考虑一类次二次二阶哈密顿系统u?−L(T)u+Wu(t,u)=0的无穷多同宿解的存在性,其中L(T)不一定是正定的,势函数W的增长率可以在(1,3/2)。利用变形喷泉定理,我们得到了二阶哈密顿系统无穷多同宿解的存在性。
In this paper, we mainly consider the existence of infinitely many homoclinic solutions for a class of subquadratic second-order Hamiltonian systems u¨− L (t) u+ W u (t, u)= 0, where L (t) is not necessarily positive definite and the growth rate of potential function W can be in (1, 3/2). Using the variant fountain theorem, we obtain the existence of infinitely many homoclinic solutions for the second-order Hamiltonian systems.
