More on the Schur group of a commutative ring

International Journal of Mathematics and Mathematical Sciences, 1985
The Schur group of a commutative ring, R, with identity consists of all classes in the Brauer group of R which contain a homomorphic image of a group ring RG for some finite group G.

The stabilized automorphism group of odometers and of Toeplitz subshifts

, 2023
We characterize the stabilized automorphism group for odometers and Toeplitz subshifts and then prove an invariance property of the stabilized automorphism group of these dynamical systems. A particular case of interest is that for torsion free odometers

Gate lattices and the stabilized automorphism group

, 2023
We study the stabilized automorphism group of a subshift of finite type with a certain gluing property called the eventual filling property, on a residually finite group $G$. We show that the stabilized automorphism group is simply monolithic, i.e.

Finite Quotients of the Automorphism Group of a Free Group

, 1977
Let G and F be groups. A G-defining subgroup of F is a normal subgroup N of F such that F/N is isomorphic to G. The automorphism group Aut (F) acts on the set of G-defining subgroups of F.

The Automorphism Group of the Hamming Code Vertex Operator Algebra

, 2000
The automorphism group of the vertex operator algebra associated to the [8,4,4] extended binary Hamming code H8 is determined, and an isomorphism of the automorphism group onto the trio stabilizer of the largest Mathieu group M24 is ...

Domains with Prescribed Automorphism Group

, 2009
Let G be the automorphism group of a bounded strictly pseudoconvex domain D subset of C(N) with a smooth (C(infinity)) boundary. Let H be a closed subgroup of G.

On the automorphism group of a linear algebraic monoid

, 1983
Let S S be a connected regular monoid with zero. It is shown that an automorphism of S S is inner if and only if it sends each idempotent of S S to a conjugate idempotent. In the language of semigroup

Automorphism group functors of algebraic superschemes

, 2023
The famous theorem of Matsumura-Oort states that if $X$ is a proper scheme, then the automorphism group functor $\mathfrak{Aut}(X)$ of $X$ is a locally algebraic group scheme. In this paper we generalize this theorem to the category of superschemes, that

Bounded Automorphisms of Groups

Journal of Algebra, 1994
Let \(G\) be the fundamental group of a graph of groups (in the sense of Bass-Serre theory). Such a group has a natural length function and thus a corresponding notion of bounded subgroups and bounded automorphisms. The general result of this paper is that an automorphism of \(G\) is bounded if and only if it is induced by isomorphisms of vertex groups

The automorphism group of Generalized Reed-Muller codes

, 1993
We prove that the automorphism group of Generalized Reed-Muller codes is the general linear nonhomogeneous group. The Generalized Reed-Muller codes are introduced by Kasami, Lin and Peterson.
