✦ Synopsis
Electronic states of multilayered cuprates are studied by the t-t 0 -t 00 -J model in the mean-field theory. The Gutzwiller approximation is introduced to include the renormalization of interlayer hopping, t ? . We find the inhomogeneous t ? 's due to a charge distribution among the CuO 2 layers in a unit cell. The Fermi surface (FS) splits in the nodal direction, while in the antinodal direction, a small value of t ? between inner layers makes four separated FS's into two degenerated FS's.
