Aug 21, 2011 at 5:42 | comment | added | WIMP | Marek: But that's exactly my question. I've repeatedly encountered referral to theories with higher order Lagrangians (I mean higher order in derivatives) as 'non-local' despite these not actually having a 'non-local' interaction of the type you are referring to. So what do they mean? | |

Aug 16, 2011 at 8:30 | comment | added | Marek | Higher order in what? Both higher powers of fields and higher powers of derivatives are not non-local. Non-locality always means interaction between fields at points separated by some distance (instead of at a single point). This can be introduced e.g. by non-polynomial functions in the Lagrangian but I am not sure what your higher-order means. In any case, you should spend some effort on making the question precise. | |
