Abstract
We combine the finite-size scaling method with a multistage real-space renormalization-group procedure to examine the Mott metal-insulator transition (MIT) on a nonpartite lattice. Based on the Hubbard model, we have found that there exists a critical point (formula presented) for the MIT with the correlation length exponent (formula presented) At the critical point, the charge gap scales with the system size as (formula presented).
