THE EXISTENCE OF POSITIVE PERIODIC SOLUTIONS FOR A CLASS OF TWO-DIMENSIONAL DELAY DIFFERENCE SYSTEMS
摘要
应用锥上的不动点定理,研究了一类二维的时滞差分系统正周期解的存在性,并得到了差分系统存在正周期解的条件。
By employing a fixed point theorem in cone,we present some sufficient conditions which guarantee the existence of positive periodic solutions for a class of two-dimensional delay difference systems.
