Automorphism groups of combinatorial Hantzsche-Wendt groups
Rafał Lutowski, Andrzej Szczepański, Richard Weidmann
Combinatorial Hantzsche-Wendt groups were introduced by W. Craig and P.A. Linnell. Every such a group , where is a natural number, encodes the holonomy action of any …

Minimal non-solvable Bieberbach groups
Rafał Lutowski, Andrzej Szczepański
It has been shown by several authors that there exists a non-solvable Bieberbach group of dimension . In this note we show that this is in fact a minimal dimension for such kin…

Flat manifolds with holonomy group Z_2^k of diagonal type
Anna Gąsior, Andrzej Szczepański
We consider relations between two families of flat manifolds with holonomy group (Z_2)^k of diagonal type. The family of real Bott manifolds and the family ${\cal GHW}…
