Asymptotic boundaries play a crucial role in the theory of general relativity. Foundational examples include the null boundary of asymptotically flat spacetimes and the conformal boundary of Anti-de Sitter space. However, not all physical settings allow for such asymptotic boundaries. In cosmology the topology of spacetime is not known, and may contain finite timelike boundaries enabling a quasilocal holographic formulation capturing the microphysics of the cosmological horizon. Finite timelike boundaries can be considered in spacetimes with arbitrary cosmological constant, and they lead to a host of fascinating questions involving well-posedness, stability, and quantum-mechanical aspects. Building from recent progress on these problems, the workshop will focus on this rapidly developing area which lies at the interface between mathematics and theoretical physics.
