 +   <hidden 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. </hidden>
