Blowing up Feynman integrals
Christian Bogner, Stefan Weinzierl
In this talk we discuss sector decomposition. This is a method to disentangle overlapping singularities through a sequence of blow-ups. We report on an open-source implementation o…

Resolution of singularities for multi-loop integrals
Christian Bogner, Stefan Weinzierl
We report on a program for the numerical evaluation of divergent multi-loop integrals. The program is based on iterated sector decomposition. We improve the original algorithm of B…
