Fray, R.L2026-05-252026-05-251977https://hdl.handle.net/10566/22879Fitting proved that if H and K are normal nilpotent subgroups of G, then so is HK (t1 l'Hilfssatz 10, p. 100). The question arises if this result could be generalized to other group theoretical propertiesenGeneralizationsubgroupstheoremnilpotentGeneralization of a theorem of fitting on the product of two normal nilpotent subgroups of a groupThesis
