Aspects of topological actions on the lattice
We consider a lattice action which forbids large fields, and which remains invariant under smooth deformations of the field. Such a "topological" action depends on one parameter, the field cutoff, but does not have a classical continuum limit as this cutoff approaches zero. We study the pr...
