DESCRIPTION:The usual Feynman graph expansions in physics lead to divergen
t powers series which are only asymptotic. This is due to the fact that th
ere are too many graphs at a given order. We propose to resolve this issue
by expanding over trees only. This is based on https://arxiv.org/abs/1712
.05670 (joint work with V. Rivasseau and V. Sazonov).\n\nhttps://indico.ma
