Editing Lattice gauge theory (section)

==Other applications==

Originally, solvable two-dimensional lattice gauge theories had already been introduced in 1971 as models with interesting statistical properties by the theorist [[Franz Wegner]], who worked in the field of [[phase transition]]s.<ref>F. Wegner, "Duality in Generalized Ising Models and Phase Transitions without Local Order Parameter", ''J. Math. Phys.'' '''12''' (1971) 2259-2272. Reprinted in [[Claudio Rebbi]] (ed.), ''Lattice Gauge Theories and Monte-Carlo-Simulations'', World Scientific, Singapore (1983), p. 60-73.

When only 1×1 Wilson loops appear in the action, lattice gauge theory can be shown to be exactly dual to [[spin foam]] models.<ref>{{cite journal |author1=R. Oeckl |author2=H.
