DESCRIPTION:Speakers: Xing Wang (The Chinese University of Hong Kong\, She
 nzhen)\n摘要：Feynman integrals are essential in perturbative quantum f
 ield theory for precision predictions. Given a family of Feynman integrals
 \, the block structures determined by sectors\, which are induced by the n
 umber of propagators\, are well-known. Recently\, we found that Feynman in
 tegrals have universal multi-layered structures\, very similar to Hodge st
 ructures in algebraic geometry\, on top of block structures. These univers
 al structures can not only simplify IBP reductions\, but also lead to \\va
 repsilon-factorized differential equations algorithmically\, no matter wha
 t geometry the integrals are related to. The algorithmic method based on t
 hese structures streamlines analytic calculations of any Feynman integrals
  and has the potential to be combined with some numeric methods.\n\n个人
 简介：王星，2024年底加入香港中文大学（深圳）理工学
 院任助理教授。2014年和2019年在北京大学获得理学学士和
 理论物理博士学位，并从2019年10月到2024年11月于德国美
 因茨大学和慕尼黑工业大学从事博士后研究工作。他的
 主要研究领域是微扰量子场论及其在粒子物理中精确预
 言，以及与宇宙学和数学的潜在的学科交叉。\nhttps://indi
