A kernel representing an inverse or fundamental solution of a linear differential operator under specified boundary conditions.
Green functions are not guaranteed to exist and are not unique until boundary, causal, or other conditions are fixed.

This is an authored directed relation from the source endpoint to the target endpoint.
For an operator and specified domain or boundary conditions, a Green function is a fundamental-solution or inverse kernel when such a distributional inverse exists.
Equip an existing carrier or structured object with additional chosen data, when such compatible data exists. Use a construction junction when several independently meaningful inputs must coexist on the same carrier or interact compatibly.

This is an authored directed relation from the source endpoint to the target endpoint.
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.
