DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CMI/10/">Non
 collinear points in the projective plane</a>\nby Ronno Das (University of 
 Chicago) as part of CMI seminar series\n\n\nAbstract\nWe will look at the 
 space of n points in the projective plane such that no three lie on the sa
 me line. There is an action of the symmetric group by permuting the points
  and we can compute the action on cohomology (for n < 7) by counting the n
 umbers of such n tuples over the finite field F_q\, with a 'twist'. Unfort
 unately for n > 6 such a computation is still hard and we expect the answe
 r for large n to be arbitrarily complicated (in the sense of Mnëv's unive
 rsality). This talk will be based on joint work with Ben O'Connor.\n
