论文摘要
我们增加了对数字拓扑中近似固定点属性（AFPP）的了解。我们表明，是树的数字图像具有AFPP。给定两个具有近似固定点特性的数字图像（x，κ）和（y，λ），其笛卡尔产物是否具有AFPP？我们探索产生肯定答案的条件。当前写作中不知道这个问题的一般答案。
We add to our knowledge of the approximate fixed point property (AFPP) in digital topology. We show that a digital image that is a tree has the AFPP. Given two digital images (X, κ) and (Y, λ) that have the approximate fixed point property, does their Cartesian product have the AFPP? We explore conditions that yield an affirmative answer. A general answer to this question is not known at the current writing.
