Automorphisms that commute with a modular automorphism

Letters in Mathematical Physics, 1984
It might be expected that the existence of automorphisms of the \(C^*\)- algebra A of quantum statistics that commute with the time automorphism, can give some insight into ergodic properties, as the existence of independent constants of motion do in classical dynamics.

Automorphisms of fibrations

Proceedings of the American Mathematical Society, 1980
Let X be a simplicial set, G a simplicial group and W ¯ G \bar WG the classifying complex of G. Then it is well known [1], [3] that the principal fibrations with base X and group G are classified by the components of the function complex (

Lip Automorphism Germ and Lip Automorphism [PDF]

Acta Mathematica Sinica, English Series, 2004
A continuous map \(f: X\to Y\) between metric spaces is called a Lip map if for every \(x\in X\), there is an open neighborhood \(U_x\) of \(x\) in \(X\) such that \(f\mid U_x\) is Lipschitz. If \(f\) is a homeomorphism and \(f\) and \(f^{-1}\) are Lip maps, \(f\) is called a Lip homeomorphism. A topological \(n\)-bundle \((E,\pi,X)\) is called a Lip \(

On Automorphism Groups of the Fields of Automorphic Functions

The Annals of Mathematics, 1972
The purpose of this paper is to determine the group of all automorphisms of the field generated by automorphic functions with respect to infinitely many mutually commensurable discrete subgroups of the group of all automorphisms of a bounded symmetric domain. In the case where either the dimension of the domain is one or the quotient spaces are compact,

Constructing an Automorphism From an Anti-Automorphism

Canadian Mathematical Bulletin, 1968
We consider the following problem: Let G be a group with distinct automorphisms β and σ and an anti-automorphism α such thatWhat can be said about G?If σ = α, σ is both an automorphism and an anti-automorphism so that G is abelian. Hence we assume that σ ≠ α.

Automorphisms of groups

Acta Applicandae Mathematicae, 1992
This is a survey article. The main sections are as follows: Automorphisms of free groups, including Gersten's Theorem and related results. The influence on a group of restricting its automorphism group. Automorphisms of soluble groups, including automorphisms of nilpotent and polycyclic groups and work related to that of Bachmuth and Mochizuki on ...

Automorphic functions and automorphic distributions

2011
Section 3.2 will provide a short “dictionary” from automorphic distribution theory (in the plane) to automorphic function theory (in II): there is slightly more information in an automorphic distribution than in an automorphic function, so that pairs of automorphic functions have to be used.

Number of Automorphisms

1990
This cardinal function is not related very much to the preceding ones. To start with, we state some general facts about the size of automorphism groups in BAs; for proofs or references, see the chapter on automorphism groups in the BA handbook.
