The Weyl tensor and the Ricci tensor can be algebraically classi ed in a Lorentzian spacetime of arbitrary dimensions using alignment the-ory. Used in tandem with the boost weight decomposition and cu...
A one parameter family of retarded linear operators on scalar fields on causal sets is introduced. When the causal set is well-approximated by 4 dimensional Minkowski spacetime, the operators are Lore...
