| 摘 要： | 1 IntroductionConsider the fOllowing Logistic modelwhere A denotes the forward difference operator defined by Ax. = xu l -- x.,{r.}7=, is a sequence of nonnegative real number, {k.}7=, is a sequence ofnonnegative integers, which satisfies j\t(n -- k.) = co) }it sup k. = co? andK is a positive constant. Obviously, K is the unique positive equilibrium pointof Eq.(1).FOr the special cases of Eq.(l)f re = r > 0 or k. == k 6 {0, 1, 2,' .}, therehave been many papers studying them. See, for exa… |
