DESCRIPTION:Title: <a href="https://researchseminars.org/talk/iccm2020/8/"
 >The geometry of Maurer-Cartan equation near degenerate Calabi-Yau varieti
 es</a>\nby Ziming Ma/馬梓銘 (The Chinese University of Hong Kong) as pa
 rt of ICCM 2020\n\n\nAbstract\nIn this talk\, we construct a dgBV algebra 
 PV(X) associated to a possibly degenerate Calabi- Yau variety X equipped w
 ith local thickening data. This gives a version of the Kodaira-Spencer dgL
 a which is applicable to degenerated spaces including both log smooth or m
 aximally degenerated Calabi-Yau. We use this to prove an unobstructedness 
 result about the smoothing of degenerated Log Calabi-Yau varieties X satis
 fying Hodge-deRham degeneracy property for cohomology of X\, in the spirit
  of kontsevich-katzarkov-pantev. If time permitted\, I will describe const
 ruction of certain class of mirror vector bundles from Lagrangian multi se
 ctions using deformation of pairs. This is based on joint works with Kwokw
 ai Chan\, Naichung Conan Leung and Yat-Hin Suen.\n
