Symmetry in Quantum Theory of Gravity

This edited collection explores current approaches to understanding space, time, and gravity within a quantum-theoretical framework. In most such approaches, the three-dimensional space of ordinary perception and action is physically fundamental, but is rather emergent from underlying structures or dynamics that can, in general, be described in terms of information flows. Processes such as measurement and computation are, therefore, fundamental to the notion of physical space

A spatial view of information

Spatial representation has two contrasting but interacting aspects (i) representation of spaces and (ii) representation by spaces. In this paper we will examine two aspects that are common to both interpretations of the theme of spatial representation, namely nerve-type constructions and refinement. We consider the induced structures, in which some of the attributes of the informational context are sampled
