Automorphism Groups of Small (3,3)-homogeneous Logics [PDF]
, 2010 We prove that (3,3)-homogeneous logics with 15 or 17 atoms are unique and for 16 atoms such logic does not exist. We also describe the automorphism groups for such logics and construct (3,3)-homogeneos logics (with 19 atoms) with either commutative ...

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

Algorithms for polycyclic-by-finite groups [PDF]
A set of fundamental algorithms for computing with polycyclic-by-finite groups is presented here. Polycyclic-by-finite groups arise naturally in a number of contexts; for example, as automorphism groups of large finite soluble groups, as quotients of ...

Mapping class groups and outer automorphism groups of free groups are C*-simple
, 2003 We prove that the reduced C*-algebras of centerless mapping class groups and outer automorphism groups of free groups are simple, as are the irreducible pure subgroups of mapping class groups and the analogous subgroups of outer automorphism groups of ...

On conjugacy separability of some Coxeter groups and parabolic-preserving automorphisms
, 2014 We prove that even Coxeter groups, whose Coxeter diagrams contain no (4, 4, 2) triangles, are conjugacy separable. In particular, this applies to all right-angled Coxeter groups or word hyperbolic even Coxeter groups. For an arbitrary Coxeter group W, we

Automorphism groups of combinatorial Hantzsche-Wendt groups [PDF]
Combinatorial Hantzsche-Wendt groups were introduced by W. Craig and P.A. Linnell. Every such a group $G_n$, where $n$ is a natural number, encodes the holonomy action of any $n+1$-dimensional Hantzsche-Wendt manifold.

The Virasoro Algebra and Some Exceptional Lie and Finite Groups
Symmetry, Integrability and Geometry: Methods and Applications, 2007 We describe a number of relationships between properties of the vacuum Verma module of a Virasoro algebra and the automorphism group of certain vertex operator algebras.
