• Endomorphism
• Polycyclic group

An endomorphism of a polycyclic group G is an automorphism if it restricts to an automorphism of the centre of the Fitting subgroup of G. The same applies to a monic endomorphism of a polycyclic-by-finite group. This extends (independent) work of D.R. Farkas and the author in the 1980s.
