Description
Sometimes it is useful to think of symmetries of quantum fields in terms of quasi-topological defects. One of the advantages of such reformulation is the remark that there are more general notions of symmetries. Recently, several examples of models in 4d with non-invertibile duality and triality symmetry defects have been constructed. In this seminar I will discuss how to exploit 6d SCFTs to reproduce some of these known examples, as well as to generate infinitely many new examples of models with non-invertibile “M-ality”symmetry defects.
