<jats:title>Abstract</jats:title><jats:p>Let <jats:italic>A</jats:italic> be a finite group acting fixed-point freely on a finite (solvable) group <jats:italic>G</jats:italic>. A longstanding conjecture is that if (|<jats:italic>G</jats:italic>|, |<jats:italic>A</jats:italic>|) = 1, then the Fitting length of <jats:italic>G</jats:italic> is bounded by the length of the longest chain of subgroups of <jats:italic>A</jats:italic>. It is expected that the conjecture is true when the coprimeness condition is replaced by the assumption that <jats:italic>A</jats:italic> is nilpotent. We establish the conjecture without the coprimeness condition in the case where <jats:italic>A</jats:italic> is an abelian group whose order is a product of three odd primes and where the Sylow 2-subgroups of <jats:italic>G</jats:italic> are abelian.</jats:p>

Fixed point free action on groups of odd order
Ercan, Gülin; Güloğlu, İsmail Ş. (Elsevier BV, 2008-7)
Let A be a finite abelian group that acts fixed point freely on a finite (solvable) group G. Assume that |G| is odd and A is of squarefree exponent coprime to 6. We show that the Fitting length of G is bounded by the length of the longest chain of subgroups of A.
On local finiteness of periodic residually finite groups
Kuzucouoglu, M; Shumyatsky, P (2002-10-01)
Let G be a periodic residually finite group containing a nilpotent subgroup A such that C-G (A) is finite. We show that if [A, A(g)] is finite for any g is an element of G, then G is locally finite.
NILPOTENT LENGTH OF A FINITE SOLVABLE GROUP WITH A FROBENIUS GROUP OF AUTOMORPHISMS
Ercan, Gülin; Ogut, Elif (2014-01-01)
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-CG(F) (h) = 1 for all nonidentity elements h is an element of H, is of nilpotent length equal to the nilpotent length of the subgroup of fixed points of H.
Equivariant Picard groups of the moduli spaces of some finite Abelian covers of the Riemann sphere
Ozan, Yıldıray (2023-03-01)
In this note, following Kordek's work we will compute the equivariant Picard groups of the moduli spaces of Riemann surfaces with certain finite abelian symmetries.
Centralizers of subgroups in simple locally finite groups
ERSOY, KIVANÇ; Kuzucuoğlu, Mahmut (2012-01-01)
Hartley asked the following question: Is the centralizer of every finite subgroup in a simple non-linear locally finite group infinite? We answer a stronger version of this question for finite K-semisimple subgroups. Namely let G be a non-linear simple locally finite group which has a Kegel sequence K = {(G(i), 1) : i is an element of N} consisting of finite simple subgroups. Then for any finite subgroup F consisting of K-semisimple elements in G, the centralizer C-G(F) has an infinite abelian subgroup A is...
