AbstractIn this article, we discuss the stability of the Nagaoka state with an infinite number of holes in the infinite-U Hubbard model. We shall rigorously show that the Nagaoka state is stable if the total number of holes Nh ≈ Nα ∧ with O≤α<2/ (d+2) as the number of lattice sites N∧ tends to infinity. Our theorem improves greatly the previous results obtained by Barbieri et al. [Phys. Rev. B 41 (1990) 11697] and by Tian [Phys. Rev. B 44 (1991) 4444]. © 1993.
