Description
In multiloop computations, choosing an integral basis that minimizes infrared divergences holds the promise of simplifying results. I describe a procedure based on analysis of Landau equations for finding sets of finite integrals. The same technique can also be applied to finding integrals which are manifestly O(ϵ). These integrals can give rise to special relations between integrals beyond those arising from integration by parts.
