Shape Optimization: Variations of Domains and Applications

This book investigates how domain dependent quantities from geometry and physics behave when the domain is perturbed. Of particular interest are volume- and perimeter-preserving perturbations. The first and second derivatives with respect to the perturbation are exploited for domain functionals like eigenvalues, energies and geometrical quantities. They provide necessary conditions for optimal domains and are useful when global approaches like symmetrizations fail. The book is exampledriven and illustrates the usefulness of domain variations in various applications.

• Comprehensive derivation of the variation formulas applying to functionals from geometry and physics.
• Presents the main tools from calculus and geometry to calculate formulas.
• Develops strategies for determination of local maxima and minima
