| Abstract: |
| In this talk, we present a new spectral inequality for the low frequencies of the Stokes operator, obtained by observing only n-1 components of the velocity field. As a consequence, we show that the cost of driving the solution of the evolutionary Stokes system to zero at a given time, using controls acting on n-1 components, is of the same order as the cost corresponding to controls acting on all components of the system. |
