On the fitting core of a formation
Published online by Cambridge University Press: 17 April 2009
Abstract
Dedicated to the memory of Bernhard H. Neumann
Not often is a formation also a Fitting class. In this article groups are exhibited that are contained in a given saturated formation and that do not lead out of this formation by forming normal products with other groups of it. This generalises a result of Cossey on T-groups and supersolvable groups.
