一类非自治Lagrange系统的周期解

Periodic Solution for a Class of Non - autonomous Lagrangian System

该文利用极小化作用原理研究了具有(a,b)一次凸位势或具有次线性非线性项的Lagrange系统的周期解,并得到了一个存在性定理.

Periodic Solution of Lagrangian system is studied with (a,b) - subconvex Ptential or sublinear nonlinearity by the least action principle ,and a existence theorem is obtained.
