Representations of the CCR in the (φ4)3 model: Independence of space cutoff
DOI: 10.1007/BF01877586
关键词:
摘要: The algebra of observables for the renormalized φ4 interaction in 3-dimensional space-time is constructed. It shown that von Neumann algebras associated with a bounded regionB are independent space cutoff which used construction Hamiltonian this interaction. This result to be useful translation invariant theory three dimensions. also gives physical criterion equivalence non-Fock representations canonical commutation relations.
