Null controllability for a parabolic-elliptic coupled system
Null controllability parabolic-elliptic systems Carleman inequalities
font style='font-size:12px;'>
2012/4/16
In this paper, we prove the null controllability of some parabolic-elliptic systems. The control is distributed, locally supported in space and appears only in one PDE. The arguments rely on fixed-poi...
