Connection of hypocoercivity and hypocontractivity via the Cayley transform
Anton Arnold, Stefan Egger, Volker Mehrmann +1
The concepts of hypocoercivity and hypocontractivity and their relationship are studied for semi-dissipative continuous-time and discrete-time evolution equations in a Hilbert spac…

Long- and short-time behavior of hypocoercive evolution equations via modal decompositions
F. Achleitner, A. Arnold, V. Mehrmann +1
The long- and short-time behavior of solutions to dissipative evolution equations is studied by applying the concept of hypocoercivity. Aiming at partial differential equations tha…
