Lattice phi(4)(2) -quantum field models with different lattice cutoffs in the free and interacting parts are constructed and their continuum limits are studied. A comparision with previously constructed continuum limits is given, in the spirit of a discussion on how limit models depend on chosen regularizations.

Abstract
Lattice phi(4)(2) -quantum field models with different lattice cutoffs in the free and interacting parts are constructed and their continuum limits are studied. A comparision with previously constructed continuum limits is given, in the spirit of a discussion on how limit models depend on chosen regularizations.File in questo prodotto:
