Rigorous proof that ground states of the SU(n) Hubbard model on the railroad-trestle lattice are fully polarized when the lower band is flat, and remain ferromagnetic for a sufficiently narrow dispersive band at one fermion per unit cell.

Ferromagnetism in the SU($n$) Hubbard model with a nearly flat band
Rigorous proof that ground states of the SU(n) Hubbard model on the railroad-trestle lattice are fully polarized when the lower band is flat, and remain ferromagnetic for a sufficiently narrow dispersive band at one fermion per unit cell.
