Numerical Analysis Seminars: Phase-field approximation of the Steiner problem and variants

Presented by Antoine Lemenant, Université Paris 7

10 October 2014 14:00 in CM105

In this talk I will present a work in collaboration with M. Bonnivard (Paris-Diderot) and F. Santambrogio (Orsay) where we propose an approximation for the Steiner problem (i.e. finding a connected set of minimal length joining a prescribed given set) by a family of elliptic type functionals, in the way of Modica-Mortola or Ambrosio-Tortorelli. The novelty in this work is a term of new type which is able to take care of the connectivity constraint.
