| Zusammenfassung |
| The implications of state dependent, finite time error growth
has been studied using singular values in a chaotic 2-dimensional map.
Earlier studies have demonstrated the superiority of the
singular values over the Lyapunov number in representing
error growth over finite time scales, since they take state dependency into account.
In this work, linearized error growth as given by singular values under operational
constraints like non-isotropic initial uncertainty and model error is considered.
It is demonstrated that the relevant singular values in the case of non-isotropic
initial uncertainty are quite different from the isotropic case. The effect of
model inadequacy on error growth is delineated. |
