Abstract

In this paper we solve in the positive the question of whether any finite set of integers, containing 0, is the mapping degree set between two oriented closed connected manifolds of the same dimension. We extend this question to the rational setting, where an affirmative answer is also given.

含零的有限集是映射度集

在本文中，我们从正面解决了这样一个问题：是否任何包含 0 的有限整数集都是两个同维度的定向闭合连通流形之间的映射度集。我们把这个问题扩展到有理集合，也给出了肯定的答案。
