Overview of the Geometries of Shape Spaces and Diffeomorphism Groups

“…Thus by definition all deformations are topology-preserving. See [21,41,131] for topologically robust approaches to shape matching.…”

An existence result for evolution equations in non-cylindrical domains

“…By inequality (6) and by the density of U in W we also get that the embedding (as done in Problem 23.10 in [10])…”

“…where A(t) is a matrix whose coefficients depend on the parameter t. More in general, given w ∈ C 1 (Q), using the change of variable G to t and formula (3) by a direct computation one gets (see also [6]) Vol. 20 (2013) An existence result for evolution equations 1729…”

On Shape Optimization for an Evolution Coupled System

“…• According to (3.10), (4.10) and (4.22), there exist shape derivatives of the solutions to the system (3.4) with the following regularity Proof The proof is standard, taking into account the specificity of the hyperbolic systems, the simplest case of the wave equation is covered in details e.g., by Cagnol and Zolésio [1], see also Sokolowski and Zolésio [12] as well as Delfour and Zolé-sio [3]. Formally, the equations for the shape derivatives are derived by an application of the Reynolds' Transport Theorem to the variational formulation of the model in variable domain setting.…”

“…We need estimates on ϕ m 3 and q m t (0) W in terms of our data. As now u m t (0) ∈ W P we can uniquely solve the second equation of (3.4) to obtain …”
