We construct a model of gravity in 1+1 spacetime dimensions in which the solutions approach the Schwarzschild metric at large $r$ and de Sitter space far inside the horizon. Our model may be viewed as a two dimensional application of the `Limiting Curvature Construction' recently proposed by two of the authors.

  1. Obstructions to Minimal Regular Black Hole Cosmologies

    gr-qc 2026-06 conditional novelty 7.0

    Obstructions from matching conditions and completeness theorems prevent minimal regular black hole models from hosting unbounded FRW daughter cosmologies.

  2. Obstructions to Minimal Regular Black Hole Cosmologies

    gr-qc 2026-06 conditional novelty 5.0

    A minimal FRW 'daughter universe' matched without a shell to an asymptotically flat regular black hole is either bounded (closed) or geodesically incomplete (flat/open), so a regular core alone cannot supply a viable ...

  3. Obstructions to Minimal Regular Black Hole Cosmologies

    gr-qc 2026-06 conditional novelty 5.0

    No-shell FRW daughters matched to asymptotically flat regular black holes are bounded if closed and past-incomplete if flat or open; a regular core alone cannot yield a viable daughter cosmology.

  4. The fate of Schwarzschild--de Sitter black holes: nonequilibrium evaporation

    hep-th 2025-11 conditional novelty 5.0

    In the Unruh–de Sitter state the anomaly flux J=(N/48π)(κ_b²−κ_c²) is positive throughout the static patch, so every neutral SdS black hole evaporates monotonically and only the Nariai limit has zero flux.
