DESCRIPTION:Title: <a href="https://researchseminars.org/talk/FOTR/8/">Ree
 s algebras of ideals generated by 2x2 minors</a>\nby Claudia Polini (Unive
 rsity of Notre Dame) as part of Fellowship of the Ring\n\n\nAbstract\nRees
  algebras of ideals of maximal minors of generic matrices are very well un
 derstood. In this\ntalk we deal with the case of sparse matrices with two 
 rows and with the case of two by two \nminors of generic matrices. We inve
 stigate the defining ideals of these algebras\, and in the first \ncase we
  prove that they are Koszul and have rational singularities or are F-ratio
 nal\, respectively. \nThis is a report on joint work with Ela Celikbas\, E
 milie Dufresne\, Louiza Fouli\, Elisa Gorla\, Kuei-Nuan \nLin\, and Irena 
 Swanson and with Hang Huang\, Michael Perlman\, Claudiu Raicu\, and Alessi
 o Sammartano.\n
