A Modica-Mortola approximation for the Steiner Problem
In this note we present a way to approximate the Steiner problem by a family of elliptic energies of Modica-Mortola type, with an additional term relying on the... -
Graphs Orientations : structures and algorithms
Orienting an undirected graph means replacing each edge by an arc with the same ends. We investigate the connectivity of the resulting directed graph. Orientations...
