However the trace does not depend on the basis chosen. This suggests to me that there is some definition of the trace of f independent of matrices (and thus coordinate-independent). SpletIn the field of applications of the energy and momentum conservation law, usually only two points are important: (1) what is the energy and momentum lost (or gained in absorption) in the emitting particle or system and (2) what is the field energy emitted in a given direction. jim attwood carlyle
