DESCRIPTION:Speakers: Florian Loebbert (Uni Bonn)\n\nThe computation of Fe
ynman integrals still represents a bottle neck for precision calculations
in quantum field theory. Recent progress goes hand in hand with the unders
tanding of new function classes and their mathematical structure. In this
talk we discuss the so-called fishnet integrals that represent an infinite
family of scalar Feynman integrals with integrable structures. In particu
lar we review the Yangian quantum group symmetry of these integrals which
extends the conformal spacetime symmetry of the associated fishnet quantum
field theories. We then focus on the specific case of fishnets in two spa
cetime dimensions and argue that these integrals compute volumes of Calabi
-Yau geometries. Here the Yangian provides a convenient tool that yields t
he Calabi-Yau differential operators\, while the geometry dictates the par
ticular linear combination of Yangian invariants which furnishes the Feynm
an integrals.\n\nhttps://indico.hiskp.uni-bonn.de/event/187/
