DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CJCS/101/">D
 iscriminants of polynomial systems</a>\nby Vladislav Pokidkin as part of C
 openhagen-Jerusalem Combinatorics Seminar\n\n\nAbstract\nThe space of all 
 systems of polynomial equations with prescribed Newton polytopes contains 
 the discriminant - the set of all systems with a degenerate root. The stud
 y of such discriminants (so called A-discriminants) was initiated by Gelfa
 nd\, Kapranov\, Zelevinsky and Sturmfels in 1990th. We make a review of ex
 isting results about the structure of discriminants and provide a conjectu
 re about its number of irreducible components and their codimensions for t
 uples of Newton polytopes with positive mixed volume.\n
