Abstract
We consider multi-edge or banana graphs b_n on n internal edges e_i with different masses m_i. We focus on the cut banana graphs Im (Phi _R(b_n)) from which the full result Phi _R(b_n) can be derived through dispersion. We give a recursive definition of Im (Phi _R(b_n)) through iterated integrals. We discuss the structure of this iterated integral in detail. A discussion of accompanying differential equations, of monodromy and of a basis of master integrals is included.
