This is an authored directed relation from the source endpoint to the target endpoint.
A propagator is a two-point correlation or Green function with a specified prescription.
The target is a member or subtype of the broader source class.

Free propagators are Green functions of kinetic operators with causal or boundary prescriptions.
A mathematical concept supplies part of the formal language, state space, representation, or analytic machinery used by a scientific or mathematical-physics concept. The source is the mathematical predecessor; this does not claim that physical content follows from mathematics alone.
