The mechanism of superconductivity in Pr$_2$Ba$_4$Cu$_7$O$_{15-\delta}$ isstudied using a quasi-one dimensional double chain model with appopriatehopping integrals, on-site $U$, and off-site repulsion $V_1$. Applying thefluctuation exchange method to this model and solving the Eliashberg equation,we obtain the doping dependence of superconductivity that is consistent withthe experiments. The superconducting gap has an extended s-wave-like form,which gives a temperature dependence of the spin lattice relaxation rate thatdoes not contradict with the experimental results.Comment: 5 pages, 8 figures, REVTe
