DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SymSem/2/">K
 ramers-Wannier-like duality defects in (3+1)d gauge theories</a>\nby Justi
 n Kaidi (SCGP) as part of Symmetry Seminar\n\n\nAbstract\nI will introduce
  a class of non-invertible topological defects in (3+1)d gauge theories wh
 ose fusion rules are the higher-dimensional analogs of those of the Kramer
 s-Wannier defect in the (1+1)d critical Ising model. As in the lower-dimen
 sional case\, the presence of such non-invertible defects implies self-dua
 lity under a particular gauging of the discrete (higher-form) symmetries. 
 I will illustrate this by means of the examples of SO(3) Yang-Mills at θ=
 π\, as well as SU(2)N=4 SYM at τ=i.\n
