====== TTP10-50 Geometric approach to asymptotic expansion of Feynman integrals ====== We present an algorithm that reveals relevant contributions in non-threshold-type asymptotic expansion of Feynman integrals about a small parameter. It is shown that the problem reduces to finding a convex hull of a set of points in a multidimensional vector space. |**Alexey Pak, Alexander Smirnov** | |** Eur.Phys.J.
