Geometric group action

In mathematics, specifically geometric group theory, a geometric group action is a certain type of action of a discrete group on a metric space.

Definition

In geometric group theory, a geometry is any proper, geodesic metric space. An action of a finitely-generated group G on a geometry X is geometric if it satisfies the following conditions:

Uniqueness

If a group G acts geometrically upon two geometries X and Y, then X and Y are quasi-isometric. Since any group acts geometrically on its own Cayley graph, any space on which G acts geometrically is quasi-isometric to the Cayley graph of G.

Examples

Cannon's conjecture states that any hyperbolic group with a 2-sphere at infinity acts geometrically on hyperbolic 3-space.

Dash

A dash is a punctuation mark that is similar to a hyphen or minus sign, but differs from both of these symbols primarily in length and function. The most common versions of the dash are the en dash (–) and the em dash (—), named for the length of a typeface's lower-case n and upper-case M respectively.

Usage varies both within English and in other languages, but the usual convention in printed English text is:

Dash Express

The Dash Express is an Internet-enabled personal navigation device manufactured by Dash Navigation Dash Express transmits information using a GPRS connection back to Dash Navigation in order to enhance traffic routing. At this time, the Dash Express can only be used in the US.

In June 2009, Research in Motion has acquired Dash Navigation

RIM is discontinuing service and support of the Dash Express product effective June 30, 2010.

Hardware

The hardware of the dash express was developed by Taiwanese hardware manufacturer FIC (First International Computers), in its Openmoko division. It was developed under the code name "Dash Cavalier" with the model number HXD8v2.
