On Damping Rates of dissipative KdV equations
Résumé
We consider here different models of dissipative Korteweg-de Vries (KdV) equations on the torus. Using a proper wave function , we compare numerically the long time behavior effects of the damping models and we propose a hierarchy between these models. We also introduce a method based on the solution of an inverse problem to rebuild a posteriori the damping operator using only samples of the solution.
