Abstract

Feynman integrals are essential in perturbative quantum field theory for precision predictions. Given a family of Feynman integrals, the block structures determined by sectors, which are induced by the number of propagators, are well-known. Recently, we found that, on top of block structures, Feynman integrals have universal multi-layered structures, very similar to Hodge structures in algebraic geometry. These universal structures can not only simplify IBP reductions, but also lead to ε-factorized differential equations algorithmically, no matter what geometry the integrals are related to. The algorithmic method based on these structures streamlines analytic calculations of any Feynman integrals and has the potential to be combined with some numeric methods.
