一类有理差分方程全局吸引性

Global Attractiveness of a Class of Rational Difference Equations

研究了一类高阶差分方程具有全局吸引性的一个充分条件,并讨论了一类高阶有理差分方程。x n=x n-s+px n-t+1 p+qx n-s x 1-max{s,t},x 2-max{s,t},…,x 0>0具备全局吸引性时参数p,q所满足的条件。

The globalattractivenessof a kind of higher order rational difference equations studied and a class of higher order rational difference equation x n=x n-s+px n-t+1 p+qx n-s x 1-max{s,t},x 2-max{s,t},…,x 0>0 is discussed.Some sufficient conditions for the equation to possess global attractive property are provided.
