abstract = {
A general framework for calculating shape derivatives for
optimization problems with partial differential equations as
constraints is presented. The proposed technique allows to obtain
the shape derivative of the cost without the necessity to involve
the shape derivative of the state variable. In fact, the state
variable is only required to be Lipschitz continuous with respect
to the geometry perturbations. Applications to inverse interface
problems, and shape optimization for elliptic systems and the
Navier-Stokes equations are given.
