Quantum causality constraints on kappa-Minkowski space-time
Quantum causality constraints on kappa-Minkowski space-time
Abstract The κ -Minkoswki space-time provides a (quantum) noncommutative deformation of the usual Minkowski space-time. However, a notion of causality is difficult to be defined in such a space with noncommutative time. In this paper, we define a notion of causality on a (1 + 1)-dimensional κ -Minkoswki space-time using …
