DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SFUQNTAG/86/
 ">Fano schemes of singular symmetric matrices</a>\nby Ahmad Mokhtar (Simon
  Fraser University) as part of SFU NT-AG seminar\n\nLecture held in K-9509
 .\n\nAbstract\nFano schemes are moduli spaces that parameterize linear spa
 ces contained in an embedded projective variety. In this talk\, I investig
 ate the Fano schemes parameterizing linear subspaces of symmetric matrices
  whose elements are all singular. I discuss their irreducibility\, smoothn
 ess\, and connectedness and show that they can have generically non-reduce
 d components. As an application\, I outline how to use the geometry of the
 se schemes to give alternative arguments for several results on subspaces 
 of singular symmetric matrices.\n
