    • The channel dependence in the vertex function (Formula presented) reduces to a mere rotation or interchange of incoming and outgoing lines. We can drop the superscript (Formula presented) when fixing the incoming and outgoing particles as in Fig. 11.

    • N. E. Bickers, (unpublished) solved the diagonal form of the parquet equations for a two-dimensional Hubbard model at high temperatures, far away from the two-particle criticality. It seems that a full solution in the critical region is still beyond the reach of the present computational facilities.
