The Renormalization Group According to Balaban - II. Large fields
J. Dimock
TL;DR
This paper explains Balaban's renormalization group method, focusing on controlling large field contributions in the scalar phi^4 model on a 3D lattice, aiding understanding of ultraviolet problems.
Contribution
It provides an expository account of Balaban's approach, specifically addressing the large field analysis in the renormalization group framework for scalar field theories.
Findings
Controlled the large field contribution to the partition function.
Applied the method to the ultraviolet problem in scalar phi^4 model.
Enhanced understanding of renormalization group techniques for large fields.
Abstract
This is an expository account of Balaban's approach to the renormalization group. The method is illustrated with a treatment of the the ultraviolet problem for the scalar phi^4 model on toroidal lattice in dimension d=3. In this second paper we control the large field contribution to the partition function.
