Outer automorphisms of supersoluble groups [PDF]
Glasgow Mathematical Journal, 2000 In this paper we study the problem of the existence on non-inner automorphisms for the class of torsion-free supersolvable groups, answering a question raised by Robinson.1991 Mathematics Subject Classification 20F16, 20F28.

Digraphs and cycle polynomials for free-by-cyclic groups [PDF]
, 2014 Let $\phi \in \mbox{Out}(F_n)$ be a free group outer automorphism that can be represented by an expanding, irreducible train-track map. The automorphism $\phi$ determines a free-by-cyclic group $\Gamma=F_n \rtimes_\phi \mathbb Z,$ and a homomorphism ...

The Existence of Outer Automorphisms of Some Groups [PDF]
Proceedings of the American Mathematical Society, 1956 F. Haimo and E. Schenkman [1] raised the question: Does a nilpotent group G always possess an outer automorphism? The answer is in the affirmative if G is finite and nilpotent of class 2, as is seen from a Schenkman's [I ] stronger result. The object of this note is to show that the answer is also in the affirmative for another family of nilpotent ...

A Kazhdan group with an infinite outer automorphism group [PDF]
Surveys in Mathematics and its Applications, 2012 D. Kazhdan has introduced in 1967 the Property (T) for local compact groups (see [D. Kazhdan, Connection of the dual space of a group with the structure of its closed subgroups, Funct. Anal. Appl. 1 (1967)]). In this article we prove that for n ≥ 3 and m

Automorphisms of complex reflection groups [PDF]
, 2009 Let $G\subset\GL(\BC^r)$ be a finite complex reflection group. We show that when $G$ is irreducible, apart from the exception $G=\Sgot_6$, as well as for a large class of non-irreducible groups, any automorphism of $G$ is the product of a central ...

Outer automorphism groups of metabelian groups
Journal of Pure and Applied Algebra, 2000 Given a group \(G\), the outer automorphism group \(\text{Out }G\) of \(G\) is given as \(\Aut G/\text{Inn }G\), the quotient of the group of all automorphisms by the group of inner automorphisms. There are a number of results about automorphisms of metablian groups which are reviewed here before the proof of the main result.

4d N $$ \mathcal{N} $$ =2 theories with disconnected gauge groups
Journal of High Energy Physics, 2017 In this paper we present a beautifully consistent web of evidence for the existence of interacting 4d rank-1 N $$ \mathcal{N} $$ = 2 SCFTs obtained from gauging discrete subgroups of global symmetries of other existing 4d rank-1 N $$ \mathcal{N} $$ = 2 ...

Random planar trees and the Jacobian conjecture
Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.Abstract We develop a probabilistic approach to the celebrated Jacobian conjecture, which states that any Keller map (i.e. any polynomial mapping F:Cn→Cn$F\colon \mathbb {C}^n \rightarrow \mathbb {C}^n$ whose Jacobian determinant is a non‐zero constant) has a compositional inverse which is also a polynomial. The Jacobian conjecture may be formulated in
