    • While we have to incorporate a weak three-dimesionality to have finite transition temperatures, approximations in 2D systems should work better for the pairing since the coherence length is expected to be greater than the magnetic correlation length.

    • The interaction can modify the shape of the Fermi surface, but ref. 23 shows that the Fermi surface (as identified from the contour of Green's function) for the triangular lattice remains disconnected for dilute band filling when the Hubbard U is switched on.
