DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BilTop/111/"
 >Survey of 3-Dimensional TQFTs and Quantum Invariants of 3-Manifolds</a>\n
 by Kursat Sozer (McMaster University) as part of Bilkent Topology Seminar\
 n\nLecture held in SA 141.\n\nAbstract\nIn this talk\, I will give a gentl
 e overview of 3-dimensional topological quantum field theories (TQFTs) and
  the corresponding quantum invariants of closed 3-manifolds. After briefly
  recalling essential algebraic notions such as pivotal\, fusion\, and modu
 lar categories\, I will describe the two main constructions of 3-dimension
 al TQFTs: the surgery approach (Witten–Reshetikhin–Turaev invariants) 
 and the state-sum approach (Turaev–Viro–Barrett–Westbury invariants)
 . I will then summarize the key comparison result involving the categorica
 l center construction\, illustrating how these two approaches yield isomor
 phic TQFTs. If time permits\, I will close by briefly mentioning extension
 s to homotopy quantum field theories (HQFTs) and highlight some recent dev
 elopments in this direction.\n
