Riassunto:

Shape Optimization is a classical field of the calculus of variations, optimal control theory and structural optimization. In this book the authors discuss the shape calculus introduced by J. Hadamard and extend it to a broad class of free boundary value problems. The approach is functional analytic throughout and will serve as an excellent basis for the development of numerical algorithms for the solution of shape optimization problems.
