use transfer matrix


$\displaystyle G_{n0}$ $\textstyle =$ $\displaystyle t_0 G_{n-1,0} + \tilde{t}_{0} G_{n+1,0}$ (180)
$\displaystyle t_0$ $\textstyle =$ $\displaystyle -(\omega S_{00}-H_{00})^{-1} (\omega S_{01}^{\dag }- H_{01}^\dag )$ (181)
$\displaystyle \tilde{t}_{0}$ $\textstyle =$ $\displaystyle -(\omega -H_{00})^{-1} (\omega S_{01}-H_{01})$ (182)


\begin{displaymath}
G_{10} = T G_{00}
\end{displaymath} (183)

where $T=T_i\vert_{i\rightarrow\infty}$


$\displaystyle (\omega S_{00} -H_{00}) G_{00} +( \omega S_{01} -H_{01} ) T G_{00}$ $\textstyle =$ $\displaystyle I$ (184)
