Non-hyperbolic 3-manifo lds can be obtained by performing Dehn fillings on 1-cusped hyperbolic 3- manifolds along exceptional slopes. In 3D-3D correspondence\, the `excepti onal' Dehn filling corresponds to the gauging of an SU(2) flavor symmetry in a superconformal field theory associated to a 1-cusped 3-manifold with `small' Chern-Simons levels. With several explicit examples\, we analyze various interesting non-perturbative IR phenomena (such as spontaneous SU SY breaking\, generation of mass gap and supersymmetry enhancement) from the `exceptional' gaugings. Interestingly\, distinguished features of t he IR phases can be captured by simple topological properties of non-hyper bolic 3-manifolds. We also find that 3D class R theories associated to cer tain classes of atoroidal non-hyperbolic manifolds always exhibit supersym metry enhancement at low energy and actually flow to 3D rank 0 N=4 SCFTs with trivial vacuum moduli space.\n LOCATION:https://researchseminars.org/talk/SymSem/9/ END:VEVENT END:VCALENDAR
