Shape Optimization and Applications

This part mainly deals with the existence (and uniqueness, if possible) of optimal shapes and their regularity. The topics have been marked by the pioneering work of Caffarelli and Alt [2], and presently are intensively developed, in particular by French and Italian schools. In general, the problem of the existence of an optimal shape is complex and difficult due to the lack of appropriate compactness in the set of domains and to poor behavior of the shape functionals with respect to the topology in the set of domains [3].
