DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TQFT/131/">Y
 oga with twisted stratifications</a>\nby Ödül Tetik (University of Vienn
 a) as part of Topological Quantum Field Theory Club (IST\, Lisbon)\n\n\nAb
 stract\nLinked spaces\, originally motivated by applications to TQFTs\, si
 multaneously simplify and generalise stratified spaces. I will briefly int
 roduce the concept and the accompanying exit-path quasi-category construct
 ion. To exhibit the nontriviality of the generalisation\, I will then cons
 ider some fundamental categories (as in "fundamental groupoid") of linked 
 spaces and realise\, from a "twist" of the complement of the trefoil knot 
 with a point defect\, a two-object category where the hom-set is the modul
 ar group PSL(2\,Z) and argue that there is no stratified space with this f
 undamental category.\n
