DESCRIPTION:Speakers: Sara Maggio (BCTP)\n\nFeynman integrals hide a pleth
 ora of interesting geometries. In this talk\, I will start by showing how 
 this connection arises\, and focus\, in particular\, on Calabi-Yau geometr
 ies. I will then present an integral with an underlying K3 surface: the th
 ree-loop banana integral with two unequal masses. The periods and the mirr
 or map can be expressed in terms of ordinary modular forms and functions. 
 I will then demonstrate how we can use ideas from cohomology to solve the 
 integral in d=2-2 eps dimensions in terms of (integrals of) modular forms 
 and functions.\n\nhttps://indico.hiskp.uni-bonn.de/event/928/
