Free Fermions on causal sets

General Relativity and Quantum Cosmology 2015-01-27 v3

Abstract

We construct a Dirac theory on causal sets; a key element in the construction being that the causet must be regarded as emergent in an appropriate sense too. We further notice that mixed norm spaces appear in the construction allowing for negative norm particles and "ghosts".
