一类维自映射有异状点的特征

Features of Homochinic Points for a Class of N-dimensional Self-mappings

设f是可降的N维自映射,则可以用可降映射的特征,给出这类自映射有异状点的特征——存在f的链回归点,但不是周期点,并且f的ω-极限点集与周期点集的交非空。

If f is a N - dimensional descendible continuous self - mapping, the characters of descendible mapping can be used. Here we present features forfwith homochinic points.
