In recent years, tropical geometry has emerged as a new tool for studying divergences of scattering amplitudes in quantum field theory and string theory. This workshop brings together experts in tropical geometry and its application to Feynman integrals with those in the study of infrared divergences in QCD with the aim of pushing the frontier of these fields. We plan to cover a broad scope of topics, ranging from factorization theorems and forest formulae for IR singularities, through computational approaches such as sector decomposition, to novel mathematical structures in polyhedral and algebraic geometry.

This workshop will be held in person only.


This workshop is sponsored by the Carl P. Feinberg Program in Cross-Disciplinary Innovation.
