Algorithm for calculating massless Feynman diagrams
Description
A method is proposed for calculating many-loop massless Feynman diagrams that uses Mellin expansions and uniqueness relations for the vertices and triangles in the Mellin representation. The algorithm makes it possible to simplify the complicated combinatorial calculations of many-loop massless Feynman diagrams in an arbitrary order for the var-phi 3 theory and also advance in the understanding of the possibilities of treating the corresponding diagrams of the var-phi 4 theory
