Abstract base class for all fields defined on a Causal Set.
A Field represents the matter content (or vacuum state) imposed on the spacetime geometry of a CausalSet. It separates the physical field parameters (like mass) from the geometric parameters of the set itself.
Properties
causet
@propertycauset:CausalSet
The causal set instance on which this field is defined.
Computes the propagator (Green's function) for this field. The specific type of propagator (Retarded, Feynman, etc.) depends on the subclass implementation.
