On higher-spin theory in two dimensions
Xavier Bekaert
(Tours (France))
Abstract:
We aim at formulating a higher-spin gravity theory around AdS2 relevant
for holography. As a first step, we investigate its kinematics by
identifying the low-dimensional cousins of the standard higher-dimensional
structures in higher-spin gravity such as the singleton, the higher-spin
symmetry algebra, the higher-rank gauge and matter fields, etc.

A new observable to decode emergent gravity
Josephine Suh
(Caltech)
Abstract:
I review the emergence of JT gravity from the SYK model, and the calculation of correlation functions in JT gravity. I motivate the need for a new observable distinct from entanglement entropy to fully decode emergent gravity, and propose as such an observable a quantum generalization of the entropy of multiple measurements on a dynamical system.
