Exact Controllability of Coupled Degenerate Wave Equations
Journal Title: 河南科技大学学报（自然科学版） - Year 2019, Vol 40, Issue 4
Abstract
The exact controllability of coupled degenerate wave equations were studied. The corresponding observability inequalities were established by multiplier method, and the boundary exact controllability of coupled degenerate wave equations were proved by Hilbert uniqueness method ( HUM) .
