Some Remarks on Commuting Fixed Point Free Automorphisms of Groups
نویسنده
چکیده مقاله:
In this article we will find necessary and sufficient conditions for a fixed point free automorphism (fpf automorphism) of a group to be a commuting automorphism. For a given prime we find the smallest order of a non abelian p-group admitting a commuting fixed point free automorphism. We prove that a group of order p3 having a commuting fpf automorphism, has a restricted structure. Moreover we prove that if a finite group admits a fpf automorphism of order 4, then the converse of Laffey’s result holds in G1.

متن کاملFixed point free automorphisms of groups related to finite fields
Let G = Fqo 〈β〉 be the semidirect product of the additive group of the field of q = p elements and the cyclic group of order d generated by the invertible linear transformation β defined by multiplication by a power of a primitive root of Fq. We study endomorphisms of G. We find an arithmetic condition on d so that every endomorphism is determined by its values on (1, 1) and (0, β). When that i...
متن کاملAutomorphisms of Free Groups Have Finitely Generated Fixed Point Sets
An automorphism of a finitely generated free group F extends to a homeomorphism of the end completion E of F. The set of fixed points of this homeomorphism is finitely generated in a certain sense. In particular this implies that the subgroup of elements fixed by the automorphism is finitely generated in the usual sense. The emphasis on E instead of F in this paper is analogous to Thurston’s st...
