DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGOON/62/">
 Matrix factorizations of some discriminants</a>\nby Eleonore Faber (Univer
 sity of Leeds\, UK) as part of Longitudinal Algebra and Geometry Open ONli
 ne Seminar (LAGOON)\n\n\nAbstract\nIn this talk\, we consider discriminant
 s of complex reflection groups. We identify certain matrix factorizations\
 , whose corresponding Cohen-Macaulay modules give a noncommutative resolut
 ion of the discriminant. We will in particular consider the family of pseu
 do-reflection groups G(r\,p\,n)\, for which one can explicitly determine t
 hese matrix factorizations that are indexed by partitions\, using higher S
 pecht polynomials (work in progress with Colin Ingalls\, Simon May\, and M
 arco Talarico).\n
