Observables in Extended Percolation Models of Causal Set Cosmology
arXiv:gr-qc/0504069 · doi:10.1088/0264-9381/23/4/018
Abstract
Classical sequential growth models for causal sets provide an important step towards the formulation of a quantum causal set dynamics. The covariant observables in a class of these models known as generalised percolation have been completely characterised in terms of physically well-defined ``stem sets'' and yield an insight into the nature of observables in quantum causal set cosmology. We discuss a recent extension of generalised percolation and show that the characterisation of covariant observables in terms of stem sets is also complete in this extension.
