| Zusammenfassung: | The controllability of the linearized KdV equation with right Neumann control
is studied in the pioneering work of Rosier [25]. However, the proof is by
contradiction arguments and the value of the observability constant remains
unknown, though rich mathematical theories are built on this totally unknown
constant. We introduce a constructive method that gives the quantitative value
of this constant. |
