Quasi-Topological Quantum Field Theories and $Z_2$ Lattice Gauge Theories

Miguel J. B. Ferreira, Victor A. Pereira, P. Teotonio-Sobrinho

We consider a two parameter family of $Z_2$ gauge theories on a lattice discretization $T(M)$ of a 3-manifold $M$ and its relation to topological field theories. Familiar models su…
