Holography for Higher Spin Gravity - Part 4

Explore the holographic duality between higher spin gravity and the free O(N) vector model in this 1-hour lecture by Robert de Mello Koch from the University of Witwatersrand. Begin with a brief review of Maldacena's original argument for holographic duality between IIB string theory on AdS5×S5 and maximally supersymmetric Yang-Mills theory. Delve into the duality between the free O(N) vector model in 2+1 dimensions and higher spin gravity on AdS4, examining the spectrum of single trace primaries in the CFT and their dual fields in higher spin gravity. Learn how the gravitational theory can be constructed using bilocal variables and collective field theory formalism. Discover recent phenomena in quantum gravity, including the quantum error correction interpretation of holography, entanglement wedge reconstruction, and the holography of information.
