Sažetak
We study the weakly interacting Hubbard model on the square lattice using a one-loop renormalization group approach. The transition temperature T-c between the metallic and (nearly) ordered states is found. In the parquet regime (T-c much greater than \mu\), the dominant correlations at temperatures below T-c are antiferromagnetic, while in the BCS regime (T-c much less than \mu\) at T-c the d-wave singlet pairing susceptibility is most divergent.
