| Apr 26, 2010 at 8:22 | comment | added | Kelly Davis | @Dylan From an effective field theory point-of-view having "infinitely many terms in your Lagrangian" is quite normal. Furthermore, as we have no T.O.E., all physical QFT theories are effective field theories and thus all have infinitely many terms in their Lagrangian. The only reason these terms don't appear normally is that they are suppressed by powers of 1/M, where M is the cut-off scale. | |

| Apr 25, 2010 at 19:23 | comment | added | Kelly Davis | From a physicist point-of-view this labeling is non-standard. However, for the context in which this appears, Kevin Costello's book on perturbative renormalization for mathematicians, it makes sense as a way of easing mathematicians in to Feynman digrams. | |
