Title of program: <b>feyngen, feyncop</b> Catalogue Id: AEUB_v1_0 Nature of problem Performing explicit calculations in quantum field theory Feynman graphs are indispensable.</br> Infinities arising in the perturbative calculations make renormalization necessary. On a combinatorial level renormalization can be encoded using a Hopf algebra [2] whose coproduct incorporates the BPHZ procedure.</br> Upcoming techniques initiated an interest in relatively large loop order Feynman diagrams which are not accessible by traditional tools.
