A generalized fixed point free automorphism of prime power order
(World Scientific Publishing, 2012-06)
Let G be a finite group and α be an automorphism of G of order pn for an odd prime p. Suppose that α acts fixed point freely on every α-invariant p′-section of G, and acts trivially or exceptionally on every elementary ...
Nilpotent length of a finite solvable group with a frobenius group of automorphisms
(Taylor & Francis, 2014-05-23)
We prove that a finite solvable group G admitting a Frobenius group FH of automorphisms of coprime order with kernel F and complement H such that [G, F] = G and C C G (F)(h) = 1 for all nonidentity elements h ∈ H, is of ...
The influence of Hughes type action
(Taylor & Francis, 2015)
We call the action of an automorphism of a finite group G a Hughes type action if it is described by conditions on the orders of elements of G-G. In the present paper we study the structure of finite group G admitting an ...
Action of a frobenius-like group with kernel having central derived subgroup
(World Scientific Publishing, 2016-09)
A finite group FH is said to be Frobenius-like if it has a nontrivial nilpotent normal subgroup F with a nontrivial complement H such that [F, h] = F for all nonidentity elements h is an element of H. Suppose that a finite ...
On the influence of fixed point free nilpotent automorphism groups
A finite group FH is said to be Frobenius-like if it has a nontrivial nilpotent normal subgroup F with a nontrivial complement H such that for all nonidentity elements . Let FH be a Frobenius-like group with complement H ...
Finite groups admitting a dihedral group of automorphisms
(Lugansk National Taras Shevchenko University, 2017)
Let D = alpha, beta be a dihedral group generated by the involutions alpha and beta and let F = alpha beta). Suppose that D acts on a finite group G by automorphisms in such a way that C-G(F)= 1. In the present paper we ...
