报告摘要:
In this work, we study the region between the event horizon and a spacelike Kasner-type singularity, and construct an exact first law for it. Formulated entirely with interior data, without reference to the exterior geometry or the asymptotic charges, the law applies not only to black holes but to any geometry with a horizon-to-Kasner structure. Starting from scalar-hairy black holes, we analyze the geometry inside the horizon. Furthermore, from the near-singularity geometry we extract a complete set of endpoint variables: the Kasner exponents, a dimensionful singularity parameter Ξ, a normalized scalar charge ΣK, and a Kasner potential MK selected by the Iyer-Wald covariant phase-space formalism.
Then, evaluating the conserved Hamiltonian variation on the event horizon and the Kasner singularity yields the exact first law: δMK = 𝒯 δS + Φe δQe + φK δΣK. The first law is tested against exact solutions (Schwarzschild, charged Einstein-Maxwell-dilaton, and scalar-hairy black-hole) and two-parameter numerical geometries; the corresponding Smarr relations are also discussed.
