Upon renormalization the interaction starts to depend on momenta and has pole-like solutions near a doping-dependent characteristic critical energy scale. Near half-filling this scale is the pseudogap temperature T*. In the overdoped regime the critical scale is the mean-field like critical temperature for d-wave superconductivity.4 pages, 2 figuresStrongly Correlated ElectronsSuperconductivitytext
