摘要

两个有限的化合物必须有多少个2胞才能有一个共同而非有限共同的覆盖?雷顿定理说两个复合体都必须有2个细胞。我们构造了一个几乎最小的例子，每个复合体中有两个2单元格。

Small non-Leighton two-complexes

Abstract How many 2-cells must two finite CW-complexes have to admit a common, but not finite common, covering? Leighton’s theorem says that both complexes must have 2-cells. We construct an almost (?) minimal example with two 2-cells in each complex.
