This EuroBroadMap working paper presents the synthesis obtained by the work package Flows and Networks. Starting from several matrices describing the international system at different periods and from different perspectives (economical, political, financial, etc.), the aim is firstly to produce a relevant partition on a world scale and, secondly, to search if an entity that could be named Europe appears. Results obtained with different methods (dominant flows, Intramax, structural equivalence, centre/ periphery) are then compared.
