This has lead to a new understanding of certain constraints on th e low-energy dynamics of QFTs\, such as QED\, or the standard model. In th is talk\, I will describe a systematic approach to deriving symmetry gener ators of Quantum Field Theories in holography. Central to this are the Gau ss law constraints in the Hamiltonian quantization of Symmetry Topological Field Theories (SymTFTs)\, which are obtained from supergravity. Cruciall y\, we realize the symmetry generators from world-volume theories of D-bra nes in holography. I will particularly focus on non-invertible symmetries\ , by presenting the application of our proposal in the holographic setup\, dual to 4d N=1 SU(M) or PSU(M) Super-Yang Mills (SYM). In the brane-pictu re\, the fusion of non-invertible symmetries naturally arises from the Mye rs effect on D-branes. In addition\, the action of the topological non-inv ertible defects t’Hooft on line is modelled by the Hanany-Witten effect. For SU and PSU SYM\, we also identify the infra-red (IR) 4d field theory from the dual gravity description\, which describes the domain-walls and c onfining/deconfining behaviour in the IR.\n LOCATION:https://researchseminars.org/talk/SymSem/24/ END:VEVENT END:VCALENDAR
