Présentation

This conference takes place between December 14th and December 16th, at the University of Tours, France. The aim of the conference is to discuss the different approaches leading to the study of random walks in cones with arbitrary big jumps. Conference funding is provided by the CNRS PEPS project «Marches avec grands pas dans le quart de plan».
