摘要
考虑时滞差分方程xn+1=xnexp[rn(1-bxpn-k-cxqn-k)],其中b>0,c>0,q>p>0,k为非负整数,{rn}为非负实数列。
The aim of this paper is to condition Delay Difference Equations x_(n+1)=x_nexp[r_n(1-bx^p_(n-k)-cx^q_(n-k))]where b>0,c>0,q>p>0,K∈Z^+,{r_n}≥0, and obtain sufficient conditions for the global attractivity of all positive solutions of a class of equations.
