DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GRT-2020/6/"
 >Cotangent complexes of moduli spaces and Ginzburg dg algebras</a>\nby Sar
 ah Scherotzke (Université du Luxembourg) as part of Geometric Representat
 ion Theory conference\n\n\nAbstract\nWe give an introduction to the notion
  of moduli stack of a dg category. \nWe explain what shifted symplectic st
 ructures are and how they are connected to Calabi-Yau structures on dg cat
 egories. More concretely\, we will show that the cotangent complex to the 
 moduli stack of a dg category $A$ admits a modular interpretation: namely\
 , it is isomorphic to the moduli stack of the Calabi-Yau completion of $A$
 . This answers a conjecture of Keller-Yeung. \n \nThis is joint work with 
 Damien Calaque and Tristan Bozec arxiv.org/abs/2006.01069\n
