DESCRIPTION:Title: <a href="https://researchseminars.org/talk/VCAS/69/">Ma
 trix Factorizations and Knörrer Periodicity</a>\nby Graham Leuschke (Syra
 cuse University\, New York\, NY) as part of IIT Bombay Virtual Commutative
  Algebra Seminar\n\n\nAbstract\nA matrix factorization of a ring element $
 f$ is a pair of square matrices so that the product (in either order) is d
 iagonal with $f$ in each diagonal entry. These were introduced by David Ei
 senbud in 1980. When the ring is regular\, matrix factorizations of $f$ co
 rrespond to maximal Cohen-Macaulay modules over the hypersurface defined b
 y $f.$ This talk will give an overview of the theory of matrix factorizati
 ons\, ending with some recent generalizations to factorizations by more th
 an two matrices.\n
