Equivalent Fixed-Points in the Effective Average Action Formalism
arXiv:1010.1530 · doi:10.1088/1751-8113/44/19/195401
Abstract
Starting from a modified version of Polchinski's equation, Morris' fixed-point equation for the effective average action is derived. Since an expression for the line of equivalent fixed-points associated with every critical fixed-point is known in the former case, this link allows us to find, for the first time, the analogous expression in the latter case.
