DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OBAGS/6/">Pi
 card Groups of the Moduli Spaces of Riemann Surfaces with Certain Finite A
 belian Symmetry Groups</a>\nby Yıldıray Ozan (ODTÜ) as part of ODTU-Bil
 kent Algebraic Geometry Seminars\n\n\nAbstract\nIn 2021\, H. Chen determin
 ed all finite abelian regular branched covers of the 2-sphere with the pro
 perty that all homeomorphisms of the base preserving the branch set lift t
 o the cover\, extending the previous works of Ghaswala-Winarski and Atalan
 -Medettoğulları-Ozan. In this talk\, we will present a consequence of th
 is classification to the computation of Picard groups of moduli spaces of 
 complex projective curves with certain symmetries. Indeed\, we will use th
 e work by K. Kordek already used by him for similar computations. During t
 he talk we will try to explain the necessary concepts and tools following 
 Kordek's work.\n
