(Nondiagonal Jordan form) Consider a linear system with a Jordan form that
is non-diagonal.
(a) Prove Proposition 6.3 by showing that if the system contains a real eigenvalue
入
=
O with a nontrivial Jordan block, then there exists an initial condition with a
solution that grows in time.
(b) Extend this argument to the case of complex eigenvalues with Reλ = 0 by
using the block Jordan form
