DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CIRGET/72/">
 Introduction to non-separated topology</a>\nby Mathieu Anel (Carnegie Mell
 on University) as part of CRM - Séminaire du CIRGET / Géométrie et Topo
 logie\n\nLecture held in PK-5115.\n\nAbstract\nClassically a topological s
 pace has a set of points. But non-separated spaces (<T1) can have a preord
 er (specialization relation). Semi-continuous functions and stratification
 s are examples of continuous functions with values in such spaces. The dev
 elopment of geometry since the 60s has motivated spaces even less separate
 d where points should have the structure of a category. Sheaves or vectors
  bundles are examples of continuous functions with values in such spaces. 
 \n\nThis talk will be an introduction to these ideas and the formalisms to
  implement it (topoi and stacks).\n\nExceptionnally\, the talk will take p
 lace in room PK 5675.\n
