A simple SRG transformation applied to nucleon-nucleon interactions leads to greatly improved convergence properties while preserving observables, and provides a method to consistently evolve many-body potentials and other operators.5 pages, 6 figures (8 figure files); references updated and acknowledgment addedNuclear TheoryStrongly Correlated ElectronsHigh Energy Physics - Phenomenologytext
