The talk discusses the structure of amplitudes which emerge in high energy physics computations. Such amplitudes appear as 'blobbed' recursions of graphs. Each of them gives rise to a multivalued function often related to (elliptic or generalized) polylogarithms.
Their monodromies relate to algebraic and combinatoric properties of graphs. We will discuss this relation in some detail.
