Forester's lattices and small non-Leighton complexes
Natalia S. Dergacheva, Anton A. Klyachko
We construct two CW-complexes and admitting a common, but not finite common, covering, where is homeomorphic to a complex with a single 2-cell.

Tiny non-Leighton complexes
Natalia S. Dergacheva, Anton A. Klyachko
How complex must two finite 2-complexes be to admit a common, but not finite common, covering? We obtain an almost answer: the minimum possible number of triangles in a pseudo-simp…

Small non-Leighton two-complexes
Natalia S. Dergacheva, Anton A. Klyachko
How many two-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 two-cells. We constru…
