Abstract: Symmetry TFTs (aka SymTFTs), and the related "sandwich
construction", provide a principled way of discussing various subtle
aspects of many systems with categorical symmetries. These objects also
appear very naturally when studying quantum field theory using
geometric methods in string theory. In this talk I will review some
elementary aspects of this description of symmetries, and explain how
it arises in string theory and holography.
