What is propagator in Feynman diagram?
Propagators in Feynman diagrams
The most common use of the propagator is in calculating probability amplitudes for particle interactions using Feynman diagrams. These calculations are usually carried out in momentum space.Is Feynman propagator symmetric?
It follows that the causal propagator ? ? ? + ? ? ? is skew-symmetric in its arguments: ? S ( x ? y ) = ? ? S ( y ? x ) .- Propagator is a model whose objective is to determine the position of satellite at any instance of time, with given acceleration and initial velocity.
