Symmetries, Microcausality and Physics on Canonical Noncommutative Spacetime
Xavier Calmet
Abstract
In this paper we describe how to implement symmetries on a canonical noncommutative spacetime. We focus on noncommutative Lorentz transformations. We then discuss the structure of the light cone on a canonical noncommutative spacetime and show that field theories formulated on these spaces do not violate mircocausality.
