DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AGSAGS/2/">A
  generic talk on irrationality</a>\nby Nathan Chen (Stony Brook University
 ) as part of American Graduate Student Algebraic Geometry Seminar\n\n\nAbs
 tract\nGiven a smooth projective variety\, there are two natural questions
  that can be asked: (1) How can we determine when it is rational? and (2) 
 If it is not rational\, can we measure how far it is from being rational? 
 There has been a great deal of recent progress towards developing invarian
 ts with the second question in mind. We will explain some new techniques i
 nvolved in bounding these invariants for certain classes of varieties.\n
