Fixed-point free action of an abelian group of odd non-squarefree exponent
(Edinburgh Mathematical Society, 2011-02)
Let A be a finite group acting fixed-point freely on a finite (solvable) group G. A longstanding conjecture is that if (|G|, |A|) = 1, then the Fitting length of G is bounded by the length of the longest chain of subgroups ...
Rank and order of a finite group admitting a Frobenius-like group of automorphisms
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 FH/[F,F] is a Frobenius group with Frobenius kernel F/[F,F]. Suppose that a finite ...

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 ...
A generalized fixed-point-free action
(World Scientific Publishing, 2013-05)
In this paper we study the structure of a finite group G admitting a solvable group A of automorphisms of coprime order so that for any x ∈ CG(A) of prime order or of order 4, every conjugate of x in G is also contained ...
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 ...
Action of a Frobenius-likegroup
We call a finite group Frobenius-like if it has a nontrivial nilpotent normal subgroup F possessing a nontrivial complement H such that [F,h]=F[F,h]=F for all nonidentity elements h∈Hh∈H. We prove that any irreducible ...
Derived length of a Frobenius-like kernel
A finite group FH is said to be Frobenius-like if it has a nontrivial nilpotent normal subgroup F called kernel which has a nontrivial complement H such that FH/[F,F]FH/[F,F] is a Frobenius group with Frobenius kernel ...
Frobenius-like groups as groups of automorphisms
A finite group F H 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, F] is a Frobenius group with Frobenius kernel F/[F, F]. Such subgroups and ...
Some sufficient conditions for the Taketa inequality
(The Japan Academy, 2013-10-15)
In this study we have obtained some sufficient conditions for the Taketa inequality namely dl(G)≤|cd(G)| for finite solvable groups G.
