Abstract The paper presents a vector approach to control problems for systems of equations. The method is described in the…

Optimal approximation of unique continuation

6 months ago

Abstract We consider numerical approximations of ill-posed elliptic problems with conditional stability. The notion of optimal error estimates is defined including…
