DESCRIPTION:[b]Speaker: Sara Maggio [/b](​University of Bonn).\n\n[b]Abstr
 act: [/b]\nFeynman integrals associated with geometries beyond the Rieman
 n sphere\, such as elliptic and Calabi–Yau geometries\, are playing an in
 creasingly important role in modern precision calculations. They appear n
 ot only in collider cross sections\, but also in gravitational-wave scatt
 ering. A powerful way to compute these integrals is through systems of di
 fferential equations\, particularly when these can be brought into canoni
 cal form\, making their singularity structure manifest. In this talk\, I 
 will present a method to construct canonical differential equations for m
 ulti-loop Feynman integrals beyond the polylogarithmic setting\, with par
 ticular emphasis on Calabi–Yau examples. After introducing the method thr
 ough the two-loop sunrise integral\, I will show how it applies to the cu
 tting-edge case of the three-loop multi-parameter banana integrals.
