Estimate of Number of Periodic Solutions of Second-Order Asymptotically Linear Difference System
We investigate the number of periodic solutions of second-order asymptotically linear difference system. The main tools are Morse theory and twist number, and the discussion in this paper is divided into three cases. As the system is resonant at infinity, we use perturbation method to study the comp...
