Oriented distance point of view on random sets with application to shape optimization
Résumé
Motivated by free boundary problems under uncertainties, we consider the oriented distance function as a way to define the expectation for a random compact or open set. In order to provide a large numbers law and a central limit theorem for this notion of expectation, we also adress the question of the convergence of the level sets of f n to the level sets of f when (f n) is a sequence of functions uniformly converging to f. We provide error estimates in terms of Hausdorff convergence. We illustrate our result on a free boundary problem.
