Emergence of space and time in holography

In the context of holographic duality, a higher-dimensional quantum gravity system is conjectured to be equivalent to a lower-dimensional conformal field theory (CFT) with a large number of degrees of freedom. This talk will introduce a framework that uses the CFT to elucidate how geometric notions inherent to the gravity system, such as spacetime subregions, various choices of time, causal structure, and spacetime connectivity, emerge in the semi-classical limit.
