DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TQFT/83/">Mo
 dels for $(\\infty\,n)$-categories with discreteness conditions</a>\nby Ju
 lie Bergner (University of Virginia) as part of Topological Quantum Field 
 Theory Club (IST\, Lisbon)\n\n\nAbstract\nThere are two ways of turning Se
 gal spaces into models for up-to-homotopy categories\, or $(\\infty\,1)$-c
 ategories: either asking that the space of objects be discrete\, or requir
 ing Rezk's completeness condition. When generalizing to higher $(\\infty\,
 n)$-categories\, both of these approaches have been taken to multisimplici
 al models\, in the form of Segal $n$-categories and $n$-fold complete Sega
 l spaces\, but models given by $\\Theta_n$-diagrams have focused on the co
 mpleteness conditions. In this talk\, we'll discuss how to get a $\\Theta_
 n$-model with discreteness conditions\, but also address the question of w
 hen these conditions can be mixed and matched with one another.\n
