DESCRIPTION:Title: <a href="https://researchseminars.org/talk/agstanford/1
 8/">Resolution and logarithmic resolution via weighted blowings up</a>\nby
  Dan Abramovich (Brown University) as part of Stanford algebraic geometry 
 seminar\n\n\nAbstract\nThis lecture combines resolution of singularities\,
  logarithmic geometry and algebraic stacks. I will not assume familiarity 
 neither with resolution of singularities nor with logarithmic geometry. I 
 report on work with Temkin and Wlodarczyk and work of Quek. Resolving sing
 ularities in families requires logarithmic geometry. Surprisingly\, trying
  to do this canonically forces us to use stack-theoretic modifications. Su
 rprisingly\, stack-theoretic modifications provides an efficient iterative
  resolution method in which the worst singularities are blown up without r
 egard to the history. Not so surprisingly\, to make exceptional divisors c
 ooperate we need logarithmic geometry again.\n
