Topological boundaries of covariant representations

چکیده
We associate a boundary $\mathcal B_{\pi ,u}$ to each covariant representation $(\pi ,u,H)$ of $C^*$-dynamical system $(G,A,\alpha )$ and study the action $G$ on its amenability properties. relate rigidity properties traces associated crossed product $C^*$-algebra faithfulness group this boundary.

Topological Representations of Matroids
One of the foundations of oriented matroid theory is the topological representation theorem of Folkman and Lawrence [8]. It says that an oriented (simple) matroid can be realized uniquely as an arrangement of pseudospheres. That there is no similar interpretation for the class of all matroids has been taken for granted. For instance, “A non-coordinatizable matroid of abstract origin may be thou...
متن کاملTopological Representations of Vector Fields
This chapter gives an overview on topological methods for vector field processing. After introducing topological features for 2D and 3D vector fields, we discuss how to extract and use them as visualization tools for complex flow phenomena. We do so both for static and dynamic fields. Finally, we introduce further applications of topological methods for compressing, simplifying, comparing, and ...
متن کاملUnitary representations of topological groups
One purpose is to isolate techniques and results in representation theory which do not depend upon additional structure of the groups. Much can be done in the representation theory of compact groups without anything more than the compactness. Similarly, the discrete decomposition of L(Γ\G) for compact quotients Γ\G depends upon nothing more than compactness. Schur orthogonality and inner produc...
متن کاملDomain representations of topological spaces
A domain representation of a topological space X is a function, usually a quotient map, from a subset of a domain onto X . Several di erent classes of domain representations are introduced and studied. It is investigated when it is possible to build domain representations from existing ones. It is, for example, discussed whether there exists a natural way to build a domain representation of a p...
متن کاملBoundaries, rigidity of representations, and Lyapunov exponents
In this paper we discuss some connections between measurable dynamics and rigidity aspects of group representations and group actions. A new ergodic feature of familiar group boundaries is introduced, and is used to obtain rigidity results for group representations and to prove simplicity of the Lyapunov exponents for some dynamical systems. Mathematics Subject Classification (2010). Primary 37...
