 BAF is stationary, ie, 6S = 0, for variations about correct path, provided the initial and final configurations are held fixed. On the other hand, if we permit infinitesimal changes of the trajectories xl(t) at the initial and final times, including alterations...  Classical Electrodynamicsby Julian Schwinger, Lester L.
