I would like to thank the Newton Institute and the organizers of the program. I would also like to thank the referee for carefully reading the manuscript and for some valuable comments. During the writing of this paper I was supported by the Danish National Research Foundation through the Centre for Symmetry and Deformation (DNRF92) and by the Research Training Group1670 “Mathematics inspired by String theory and Quantum Field Theory”.30340586engHopf algebrasTensor categoriesSymmetric monoidal categoriesGeometric invariant theory3-manifolds invariantsFrobenius–Schur indicatorsQA MathematicsQAJournal article10.1016/j.aim.2017.02.020https://arxiv.org/abs/1506.00314v2311
