k维环面上坐标自映射下拓扑熵的一个下界

Lower Bound of Topological Entropy of Coordinate Self-maps on k-Dimension Torus

给出了k维环面上坐标自映射下拓扑熵的一个下界,最后，还指出了k维环面上渐近Reidemeister数严格大于渐近Nielsen数的情形，并说明了文[3]（或文[4]）中引理1为该文的一个特例．

In this paper, we give a lower bound of topological entropy of coordinate selfmaps on k-dimension torus. The last of this paper, we skow the R∞(f)>N∞(f) and proved that lemma 1 in [3] is a special case in this paper.
