Small non-Leighton two-complexes
Published online by Cambridge University Press: 05 September 2022
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.
