The boundary imprint of local bulk dynamics in general geometries

I will explore the boundary imprint of bulk lightcones in spacetimes with boundaries, motivated by the holographic correspondence. These lightcones can be observed whenever a localized event takes place in the bulk. The associated boundary surfaces (hyperboloids) reveal the bulk conformal metric. Moreover, studying the amplitude of the process allows us to fix the conformal factor. I will explain how to study these processes and their corresponding boundary surfaces using a Hamilton-Jacobi description, and investigate the implications regarding causality.
