Overcoming Nonrenormalizability
John R. Klauder
A suitable counterterm for a Euclidean space lattice version of ϕ^4_n theories, n\ge 4, is combined with several additional procedures so that in the continuum limit the resultant…
Quantization of Constrained Systems
John R. Klauder
The present article is primarily a review of the projection-operator approach to quantize systems with constraints. We study the quantization of systems with general first- and sec…
Nonrenormalizability and Nontriviality
John R. Klauder
A redesigned starting point for covariant ϕ^4_n, n\ge 4, models is suggested that takes the form of an alternative lattice action and which may have the virtue of leading to a nont…
Coherent-state path-integral approach for constrained fermion systems
Georg Junker, John R. Klauder
The coherent-state path-integral representation for the propagator of fermionic systems subjected to first-class constraints is constructed. As in the bosonic case the importance o…
Poisson Distributions for Sharp-Time Fields: Antidote for Triviality
John R. Klauder
Standard lattice-space formulations of quartic self-coupled Euclidean scalar quantum fields become trivial in the continuum limit for sufficiently high space-time dimensions, and i…
