DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/61/">T
 opological symmetries and their gaugings in 2dCFT and 3dTFT</a>\nby Ingo R
 unkel (Universität Hamburg) as part of NHETC Seminar\n\n\nAbstract\nThe s
 tudy of topological defects in quantum field theory as seen a wealth of ac
 tivity recently leading to many interesting insights\, for example the exp
 licit realization of non-invertible topological defects in higher dimensio
 nal QFTs via the gauging of higher form symmetries\, or the description of
  the higher algebraic structures inherent in these topological defects. \n
 \nIn this talk\, I would like to focus on low-dimensional examples\, where
  such defects and their properties have been investigated for some time al
 ready. I would like to exhibit some of the properties of topological defec
 ts in two-dimensional conformal field theory and in three-dimensional topo
 logical field theory\, and show some of the structural insights into 2dCFT
  and 3dTFT one can gain with the help of defects. In this way\, the well-u
 nderstood low-dimensional case might serves as a source of ideas and as a 
 test-case for higher dimensional constructions.\n
