Scheme independence as an inherent redundancy in quantum field theory
arXiv:hep-th/0102037 · doi:10.1142/S0217751X01004724
Abstract
The path integral formulation of Quantum Field Theory implies an infinite set of local, Schwinger-Dyson-like relations. Exact renormalization group equations can be cast as a particular instance of these relations. Furthermore, exact scheme independence is turned into a vector field transformation of the kernel of the exact renormalization group equation under field redefinitions.
