ABSTRACT
In this chapter we consider boundary controllability for systems described by linear partial differential equations. So in the rest of this chapter we will assume that Ω denotes an open bounded set in R n such that () { the boundary Γ of Ω is an ( n − 1 ) dimensional infinitely differentiable variety, Ω being locally on one side of Γ , https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203755426/d9706a82-faf3-4225-933c-afa32800295e/content/eq1301.tif"/>
