Some Remarks on Group Bundles and C(X)-Dynamical Systems

نویسنده

چکیده

We give a characterization of C(X)-dynamical systems (B, G) such that the relative commutant of the fixed point algebra A := B is minimal (i.e. A′ ∩ B = (A∩A′)∨ (B ∩B′)) in terms of a field of C*-algebras over a suitable coset bundle. Here G is intended as the space of sections of a compact group bundle over X , so that it is a compact group when X is a single point. AMS Subj. Class.: 46L05, 55R10, 22D45

Some Remarks on Group Bundles and dynamical C*-systems

We give a characterization of dynamical C*-systems such that the relative commutant of the fixed-point C*-algebra is minimal (i.e., it is generated by the centre of the given C*-algebra and the centre of the fixed-point C*-algebra), in terms of suitable C*-algebra bundles. The group acting on the C*-algebra is the (noncompact, in general) space of sections of a compact group bundle. AMS Subj. C...

Some Remarks on Group Bundles and C*-dynamical systems

We introduce the notion of fibred action of a group bundle on a C0(X)algebra. By using such a notion, a characterization in terms of induced C*-bundles is given for C*-dynamical systems such that the relative commutant of the fixed-point C*-algebra is minimal (i.e., it is generated by the centre of the given C*-algebra and the centre of the fixed-point C*algebra). A class of examples in the set...

A COVERING PROPERTY IN PRINCIPAL BUNDLES

Let $p:Xlo B$ be a locally trivial principal G-bundle and $wt{p}:wt{X}lo B$ be a locally trivial principal $wt{G}$-bundle. In this paper, by using the structure of principal bundles according to transition functions, we show that $wt{G}$ is a covering group of $G$ if and only if $wt{X}$ is a covering space of $X$. Then we conclude that a topological space $X$ with non-simply connected universal...

On the Notion of Fuzzy Shadowing Property

This paper is concerned with the study of fuzzy dynamical systems. Let (XM ) be a fuzzy metric space in the sense of George and Veeramani. A fuzzy discrete dynamical system is given by any fuzzy continuous self-map dened on X. We introduce the various fuzzy shad- owing and fuzzy topological transitivity on a fuzzy discrete dynamical systems. Some relations between this notions have been proved.

Canonical Heights, Invariant Currents, and Dynamical Systems of Morphisms Associated with Line Bundles

We construct canonical heights of subvarieties for dynamical systems of several morphisms associated with line bundles defined over a number field, and study some of their properties. We also construct invariant currents for such systems over C. Introduction Let X be a projective variety over a field K and fi : X → X (i = 1, · · · , k) morphisms over K. Let L be a line bundle on X, and d > k a ...
