【 摘 要 】

We investigate the filling dependence of the zigzag Hubbard ladder, which is a relevant model to the recently synthesized quasi-one-dimensional super conductor Pr2Ba4Cu7O15-delta(Pr247). Using the density matrix renormalization group method, we calculate chemical potential-electron density (mu-rho) curve of the model and then discuss the relation between the oxygen-deficiency and transition temperature in Pr247.
