| Jul 8 at 6:42 | comment | added | Abezhiko | @Luke__ Glad to help ;) I mentionned gauge freedom in reference to Maxwell's equations, where the electromagnetic potentials can be designed freely to a certained extent (but not at absolute will, however) by fixing a so-called gauge, in such a way that the electromagnetic fields stay the same at the end. Analogously, it is possible to choose a homogeneous solution and add it to the fundamental solution, so that the result is still a Green function. In Petrini's example, it allows us to work with a shorter/simpler and moreover even expression for the Green function. | |
