Title: Contiguous relations for Feynman integrals Abstrakt: Difference equations between Feynman integrals are an essential tool for perturbative calculations in quantum field theory. I begin with a review of several established approaches to generate and solve these equations. Then I suggest to augment those by new methods based on integral representations and in particular `contiguous' difference equations, which shift only a single index at a time.
