Exact controllability for problems of transmission of the plate equation with lower-order terms
We consider the exact controllability for the problem of transmission of the plate equation with lower-order terms. Us- ing Lions' Hilbert Uniqueness Method (HUM for short), we show that the system is exactly controllable in L 2 () H 2 () . We also obtain some uniqueness theorems for the problem of trans- mission of the plate equation and for the operator a(x) 2 +q.
