Stable rational cohomology of automorphism groups of free groups and the integral cohomology of moduli spaces of graphs [PDF]

, 2002
It is not known whether or not the stable rational cohomology groups H*(Aut(F[infinity]);Q) always vanish (see Hatcher in [5] and Hatcher and Vogtmann in [7] where they pose the question and show that it does vanish in the first 6 dimensions).

On the Structure of Weyl-Type, Witt-Type, and Non-Associative Algebras over Expolynomial Rings

Mathematics
This paper introduces a generalized class of Weyl-type, Witt-type, and non-associative algebras constructed over an exponential–polynomial (expolynomial) framework.

On Some Properties of the Operator, Defined on Class of Analytic in the Half-Plane Functions

Nonlinear Analysis, 2004
In present paper the properties of the operator introduced by authors, which is defined on special class of n-normalized analytic in the half-plane functions are investigated. This operator is closely related with automorphism of a half-plane.

Quantum automorphism groups of trees

, 2023
We give a characterisation of quantum automorphism groups of trees. In particular, for every tree, we show how to iteratively construct its quantum automorphism group using free products and free wreath products.

Geometric automorphism groups of graphs [PDF]

, 2007
Constructing symmetric drawings of graphs is NP-hard. In this paper, we present a new method for drawing graphs symmetrically based on group theory. More formally, we define an n-geometric automorphism group as a subgroup of the automorphism group of a ...

Automorphism Groups of Quandles [PDF]

, 2011
This thesis arose from a desire to better understand the structures of automorphism groups and inner automorphism groups of quandles. We compute and give the structure of the automorphism groups of all dihedral quandles.

The automorphism tower problem

, 1985
It is shown that the automorphism tower of an infinite centerless group terminates. For each ordinal α \alpha , a group is constructed whose automorphism tower terminates in exactly α \alpha steps.
