DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ZAG/95/">Inv
 ersion of adjunction for quotient singularities</a>\nby Yusuke Nakamura (U
 niversity of Tokyo) as part of ZAG (Zoom Algebraic Geometry) seminar\n\n\n
 Abstract\nThe minimal log discrepancy is an invariant of singularities def
 ined in birational geometry\, and it is related to the conjecture of termi
 nation of flips. In this talk\, we will discuss the minimal log discrepanc
 ies of quotient singularities. I will show that the PIA (precise inversion
  of adjunction) conjecture holds for quotient singularities. The main tool
  of this talk involves the theory of the arc space of a quotient singulari
 ty established by Denef and Loeser. This is joint work with Kohsuke Shibat
 a.\n
