Embedding periodic maps of surfaces into those of spheres with minimal dimensions
摘要
It is known that any periodic map of order n on a closed oriented surface of genus g can be equivariantly embedded into Sm for some m. In the orientable and smooth category, we determine the smallest possible m when n ⩾ 3g. We show that for each integer k > 1, there exist infinitely many periodic maps such that the smallest possible m is equal to k.
