On groups with formational subnormal Sylow subgroups
(De Gruyter, 2018)
We investigate a finite group G with F-subnormal Sylow subgroups, where F is a subgroup-closed formation and A1A⊆F⊆NA. We prove that G is soluble and the derived subgroup of each metanilpotent subgroup is nilpotent. We ...
On groups with biprimary subgroups of even order
(2017)
We investigate groups in which maximal subgroups of even order are primary or biprimary. We also research
soluble groups with restriction on a number of prime devisors of some
proper subgroup orders. We give applications ...
Finite groups with restrictions on normal subgroups
(2016)
We investigate the structure of finite soluble groups all whose proper
normal subgroups belong to some class of groups, namely a Fitting class and the class
of all supersoluble groups.
