arxiv_dataset-57771411.7728 | A uniqueness of periodic maps on surfaces
math.GT
Kulkarni showed that, if g is greater than 3, a periodic map on an oriented
surface S_g of genus g with order more than or equal to 4g is uniquely
determined by its order, up to conjugation and power. In this paper, we show
that, if g is greater than 30, the same ph... | arxiv topic:math.GT |
