DESCRIPTION:Speakers: Ilarion Melnikov (James Madison University)\n\nI wil
 l discuss the role played in mirror symmetry by torsion groups in the inte
 gral cohomology of a Calabi-Yau 3-fold.  Building on work from the mid 90
 s\, I will clarify the relation of these groups to global symmetries of th
 e associated worldsheet superconformal field theory and flat abelian gerbe
 s and discuss the mirror structures.  The talk will be based on preprint 
 2407.07635.\n\nhttps://indico.hiskp.uni-bonn.de/event/1023/
