研究了一類非自治二階哈密頓系統(tǒng)周期解的存在性,在非線性項(xiàng)F(t,x)= F1(t,x)+F2(t,x)滿足條件(A)及F1(t,x),F(xiàn)2(t,x)分別滿足一定條件時(shí),通過(guò)使用極小作用原理獲得了一個(gè)新的周期解的存在性定理。

Existence of periodic solutions for a class of non-autonomous second order Hamiltonian systems is studied.When the nonlinear term F(t,x)=F1(t,x)+F2(t,x)satisfies condition(A)and F1(t,x),F(xiàn)2(t,x)satisfy many conditions,one new existence theorem of periodic solution is obtained by the least action principle.
