Homoclinic solutions of some second-order non-periodic discrete systems Yuhua Long College of Mathematics and Information Sciences Guangzhou University Guangzhou 510006 P. R. China Email address longyuhua214@ Abstract In this article we discuss how to use a standard minimizing argument in critical point theory to study the existence of non-trivial homoclinic solutions of the following second-order non-autonomous discrete systems A2xra_1 AAxn L n xn v n xn 0 n 2 Z without any periodicity assumptions. Adopting some reasonable assumptions for A and L we establish that two new criterions for guaranteeing above systems have one non-trivial homoclinic solution. Besides 1 that in some particular .
