DESCRIPTION:Speakers: Mehregan Doroudiani (AEI Potsdam)\n\nIn the calculat
 ion of the perturbative amplitude of superstring theory at one loop\, modu
 lar graph functions (MGFs) emerge as notable mathematical constructs. Thes
 e MGFs\, representing Feynman diagrams on the surface of a torus\, must be
  integrated over the fundamental domain. My talk will introduce MGFs\, elu
 cidate their generating series\, and delve into the concept of equivarianc
 e\, playing a key role in classifying MGFs. Additionally\, I will cover re
 cent advancements in understanding the generating series of MGFs and the i
 ntegration of MGFs over the fundamental domain. The contents of this talk 
 are derived from 2209.06772 and ongoing works.\n\nhttps://indico.hiskp.uni
