English abstract:
We review the Lyapunov functional method for linear ODEs
and give an explicit construction of such functionals that yields sharp decay estimates, including an extension to defective ODE systems. As an application, we consider three evolution equations, namely the linear convection-diffusion equation, the two velocity BGK model and the Fokker{Planck equation.
Adding an uncertainty parameter to the equations and analyzing its
linear sensitivity leads to defective ODE systems.
