We reorder the eigenvalue pair so that $S_{ii}/T_{ii}$ with modulus
less than one would be in the left-upper part.
\li The Blachard--Kahn stability argument implies that the pairs
with modulus less that one will be in and only int $S_{11}/T_{11}$.
\li The Blanchard--Kahn stability argument implies that the pairs
with modulus less that one will be in and only in $S_{11}/T_{11}$.
The exploding paths will be then eliminated when
$$
\left[\matrix{Z_{11}^T&Z_{21}^T\cr Z_{12}^T&Z_{22}^T}\right]
\left[\matrix{I\cr X}\right]\left[g_{y^*}^*\right]=
\left[\matrix{I\cr X}\right]=
\left[\matrix{Y\cr 0}\right]
$$
From this we have, $Y=Z_{11}^{-1}$, and $X=Z_{21}Y$, or equivalently
