DESCRIPTION:Title: <a href="https://researchseminars.org/talk/agstanford/1
 39/">An overview of measures of irrationality</a>\nby Nathan Chen (Columbi
 a University) as part of Stanford algebraic geometry seminar\n\nLecture he
 ld in 384-I (unusual date and location).\n\nAbstract\nThe classical questi
 on of determining which varieties are rational has led to a huge amount of
  interest and activity. On the other hand\, one can consider a complementa
 ry perspective - given a smooth projective variety whose nonrationality is
  known\, how "irrational" is it? I will survey what is currently known\, w
 ith an emphasis on surfaces and open problems.\n
