RT Journal Article T1 A proposal of a Monte Carlo renormalization group transformation A1 Fernández Pérez, Luis Antonio A1 Muñoz Sudupe, Antonio A1 Ruiz Lorenzo, J. J. A1 Tarancón, A. AB We propose a family of renormalization group transformations characterized by free parameters that may be tuned in order to reduce the truncation effects. As a check we test them in the three dimensional XY model. The Schwinger-Dyson equations are used to study the renormalization group flow.
