关于欧几里得空间子集的渐近大小

On the asymptotic magnitude of subsets of Euclidean space

Tom Leinster, Simon Willerton

摘要:

幅是有限度量空间的一个标准不变量,它起源于范畴论;它类似于有限集合的基数。本文通过用有限子集逼近欧几里得空间的某些紧子集,定义并计算了线段、圆和康托集的大小。据观察,这些渐近满足容斥原理,将它们与多凸集的内在体积。

英文摘要:

Magnitude is a canonical invariant of finite metric spaces which has its origins in category theory; it is analogous to cardinality of finite sets. Here, by approximating certain compact subsets of Euclidean space with finite subsets, the magnitudes of line segments, circles and Cantor sets are defined and calculated. It is observed that asymptotically these satisfy the inclusion-exclusion principle, relating them to intrinsic volumes of polyconvex sets.
