Edit summary: ←Created page with 'In mathematics, a '''fibration of graphs''', or '''graph fibration''', is a morphism of directed graphs that satisfies a unique lifting property analogous to that of a fibration in topology. Intuitively, the target (''base'') graph is "covered" by the source (''total'') graph in such a way that each arc of the base can be uniquely lifted to any node in the fibre of its target. The concept has been independently discovered...'
