We compare the topological Milnor fibration and the motivic Milnor fibreby introducing a common extension : the complete Milnor fibration. This extension is constructed using either logarithmic geometry or an oriented (multi)graph construction, for a complex regular function with only normal crossings. The comparison uses quotients by the action of the group of positive real numbers. We study moreover how this model changes under blowings-up. Joint work with J.-B. Campesato and A. Parusinski.
