Exact renormalization group approach in scalar and fermionic theories
arXiv:hep-th/9702082 · doi:10.1142/S0217979298000740
Abstract
The Polchinski version of the exact renormalization group equation is discussed and its applications in scalar and fermionic theories are reviewed. Relation between this approach and the standard renormalization group is studied, in particular the relation between the derivative expansion and the perturbation theory expansion is worked out in some detail.
