Does lattice gauge theory have anything (perhaps a lot!) nontrivial to do with spin foams in QG? Is the spin foam approach to QG a lattice gauge theory? Thank-you! (Wed, June 8th, 2005). :-)
- Not really. Lattice gauge theory uses the lattice as a regulator, but takes the size of the lattice to zero. It's purely a matter of calculational convenience. Spin foams, tho they do regulate your theory by setting a smallest unit of area, are supposed to be real physical entities. Also, spin foams are arbitrarily-connected graphs rather than regular lattices. -- Xerxes 21:31, 2005 Jun 8 (UTC)
[edit] merge suggested
OK, I really suggest merging Lattice field theory and this one in some sensible way, then perhaps renaming the whole "lattice field theory" as that is more generic. Otherwise you don't know what to link to from other articles. If, however, there really is something more specific to "lattice gauge theories" that cannot be covered in the main article, then a new article can be started. But I am really doubtful; the distinction between "lattice theories with pure gauge actions" and "lattice theories with fermions/particles in it" doesn't seem to warrant having separate articles, which would largely anyway just repeat each other. 131.111.8.96 22:39, 19 September 2006 (UTC)
- Sounds sensible. -David Schaich Talk/Cont 22:27, 18 November 2006 (UTC)
