P(f) = R(f) for One-Dimensional Difference Equations

将区间上一维连续自映射的结果P( f) =R( f) 推广到任意维的差分方程上去 。

A theorem of = for one-dimensional difference equations is generalized to a class of difference equations of arbitary dimension.The mapping defining these difference are such that the ith component depends only on the first i indepenclent variables.
