DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UCGEN/33/">T
 he big singularity category of a non-affine scheme</a>\nby Sergio Estrada 
 (University of Murcia) as part of UCGEN - Uluslararası Cebirsel GEometri 
 Neşesi\n\n\nAbstract\nA classic result of Buchweitz shows that the singul
 arity category of a Gorenstein local ring A is triangulated equivalent to 
 the stable category of finitely generated Gorenstein projective A-modules 
 and to the homotopy category of totally acyclic complexes of finitely gene
 rated projective A-modules. In this talk we present a non-affine version o
 f this result. To achieve this we will define a "big" version of Orlov´s 
 singularity category.The talk is based on a project developed with Lars Ch
 ristensen (Texas Tech University) and Peder Thompson (Norwegian University
  of Science and Technology).\n
