A Proposal for symTFTs and symThs from Holography

We propose an embedding of the symTFT construction in (finite cut-off) holography. The proposal passes several non-trivial consistency checks reproducing the expected symTFTs in various cases, including the recently discussed symTFT for the 1-form symmetry of 4d $\mathcal{N}=4$ SYM. Moreover, we comment on the possibility of unifying the symTFT and the symTh descriptions via the democratic formulation of Supergravity, using the 4d $\mathcal{N}=4$ SYM theory as an example.
