The automorphism group of accessible groups
In this article, we study the outer automorphism group of a group G decomposed as a finite graph of group with finite edge groups and finitely generated vertex groups with at most one end. We show that Out(G) is essentially obtained by taking extensions of relative automorphism groups of vertex groups, groups of Dehn twists and groups of automorphisms of free products. We apply this description...
متن کاملBoundaries of strongly accessible hyperbolic groups
We consider splittings of groups over finite and two-ended subgroups. We study the combinatorics of such splittings using generalisations of Whitehead graphs. In the case of hyperbolic groups, we relate this to the topology of the boundary. In particular, we give a proof that the boundary of a one-ended strongly accessible hyperbolic group has no global cut point. AMS Classification 20F32
متن کاملAccessible Design for Communication on the Web
Web site design that does not conform to emerging accessibility standards and legislation will be increasingly under attack. In order to facilitate Web-based computer mediated communication to the disabled, extensive guidelines and laws are now in place to guide designers of content, development tools and devices and software used by those with disabilities. This chapter discusses accessibility...
متن کاملTowards Collaboration on Accessible UML Models
The Unified Modeling Language (UML) is one of the most used software description languages. Its graphical syntax, however, impedes visually impaired people from taking part in discussions. Editors for textual and graphical UML syntaxes exist but lack advanced support for collaborative editing. In this paper, we describe our plans on implementing a collaborative editing environment consisting of...
متن کاملMultiBeeBrowse - Accessible Browsing on Unstructured Metadata
Growing abundance of information on the Internet, especially the Next Generation Internet, poses even more challenges on more efficient information management; hence it has brought attention of the researchers to the faceted navigation. Existing solutions, however, do not address the majority of users, who are still inexperienced in using the faceted navigation solutions or who do not understan...
