Instability of Anti-de Sitter Spacetime for the Einstein-Scalar Field System
Explore a rigorous proof of the Anti-de Sitter (AdS) instability conjecture in the context of the spherically symmetric Einstein-scalar field system. Delve into the dynamics of the Einstein equations with a negative cosmological constant, examining how small perturbations to AdS spacetime's initial data can lead to black hole formation under specific conditions. Discover the intricate process of designing unstable initial data through carefully crafted localized matter beam configurations. Gain insights into estimating energy exchanges between interacting beams over extended time periods and understanding beam decoherence rates. Consider potential avenues for extending these concepts to the vacuum case, enhancing your understanding of gravitational dynamics and spacetime instability.
