On the influence of the coupling on the dynamics of under-observed cascade systems of PDE’s (ENGLISH)
[ 講演概要 ]
We consider observability of coupled dynamical systems of hyperbolic and parabolic type when the number of observations is strictly less that the number of unknowns. A main issue is to understand how the lack of observations of certain components is compensated by the coupling information. This talk will present a mathematical approach based on energy methods and some recent positive and negative results on these questions.
