- Abstract:
- This paper concerns the existence of multiple homoclinic orbits for the second-order Hamiltonian system (¨overz)-L(t)z+Wz(t, z)=0, where L∈C(R, RN22)is a symmetric matrix-valued function and W(t, z)∈C11(R×RN, R)is a nonlinear term. Since there are no periodic assumptions on L(t)and W(t, z)in t, one should overcome difficulties for the lack of compactness of the Sobolev embedding. Moreover, the nonlinearity W(t, z)is asymptotically linear in z at infinity and the system is allowed to be resonant, which is a case that has never been considered before. By virtue of some generalized mountain pass theorem, multiple homoclinic orbits are obtained.
- 研究了二阶Hamilton系统(¨overz)-L(t)z+Wz(t, z)=0多个同宿轨的存在性, 其中L∈C(R, RN2)是一对称矩阵值函数, W(t, z)∈C1(R×RN, R)是非线性项.由于L(t)和W(t, z)关于t没有周期性假设, 需要克服Sobolev嵌入缺乏紧性的困难.而且, 这里非线性项W(t, z)关于z在无穷远处是渐进线性的且系统允许出现共振, 这一情形之前未被考虑过.借助于广义的山路定理, 得到了多个同宿轨.
