A power counting theorem for Feynman integrals on the lattice
- T. Reisz
- Mathematics
- 1 March 1988
A convergence theorem is proved, which states sufficient conditions for the existence of the continuum limit for a wide class of Feynman integrals on a space-time lattice. A new kind of a…
Power Counting and Renormalization in Lattice Field Theory
- T. Reisz
- Physics
- 1988
In an Euclidean quantum field theory a space-time lattice provides a quite natural non-perturbative ultraviolet cutoff. This has lead to a variety of non-perturbative methods. Observable physics has…
A convergence theorem for lattice Feynman integrals with massless propagators
- T. Reisz
- Physics, Mathematics
- 1 December 1988
It is shown that for non-vanishing lattice spacing, conventional infrared power counting conditions are sufficient for convergence of lattice Feynman integrals with zero-mass propagators. If these…
Renormalization of Feynman integrals on the lattice
- T. Reisz
- Physics
- 1 March 1988
A perturbative renormalization procedure is proposed which applies to massive field theories on a space-time lattice and is analogous to the BPHZ finite part prescription for continuum Feynman…

Critical phenomena with convergent series expansions in a finite volume
- H. Meyer-Ortmanns, T. Reisz
- Physics, Mathematics
- 10 April 1996
Linked cluster expansions are generalized from an infinite to a finite volume. They are performed to 20th order in the expansion parameter to approach the critical region from the symmetric phase. A…
