DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ATP2022/3/">
 Kite and Triangle diagrams through Symmetries of Feynman Integrals</a>\nby
  Subhajit Mazumdar (Seoul National University) as part of Advances in Theo
 retical Physics 2022\n\n\nAbstract\nThe Symmetries of Feynman Integrals (S
 FI) is a method for evaluating Feynman Integrals which exposes a novel con
 tinuous group associated with the diagram which depends only on its topolo
 gy and acts on its parameters. Using this method we study the kite diagram
  (a two-loop diagram with two external legs) and the most general triangle
  diagram (one-loop diagram with three external legs) with arbitrary masses
  and space-time dimensions. Generically\, this method reduces a Feynman in
 tegral into a line integral over simpler diagrams. We identify the locus/l
 oci in parameter space where the integrals further reduce to a mere linear
  combination of simpler diagrams. We generalize and revisit some known res
 ults.\n
