A short overview of black hole entropy in alternative gravitational theories is presented. Motivated by the recent attempts to explain the cosmic acceleration without dark energy, we focus on metric and Palatini f(R) gravity and on scalar-tensor theories.

  1. Entropic route to Brown-York tensor: A unified framework for null and timelike hypersurfaces

    gr-qc 2026-05 unverdicted novelty 6.0

    An entropy functional yields the Brown-York tensor via conjugate momentum projection, unifying null and timelike hypersurfaces and reproducing equations in scalar-tensor gravity.

  2. GW250114: testing Hawking's area law and the Kerr nature of black holes

    gr-qc 2025-09 accept novelty 5.0

    GW250114 data confirm the remnant black hole ringdown frequencies lie within 30% of Kerr predictions and that the final horizon area is larger than the sum of the progenitors' areas to high credibility.

  3. First Law for Nonsingular Black Holes in 2D Dilaton Gravity

    gr-qc 2026-03 reject novelty 4.0

    For 2D nonsingular dilaton black holes with A=f+c, the first law holds with energy E=-c/2 once the asymptotic time translation is properly normalized.

  4. Gravitational wave constraints on corrections to Bekenstein-Hawking Area Formula in classical F(R) gravity and quantum GR : implications for theory parameters

    gr-qc 2026-07 conditional novelty 2.0

    Assuming an extra 'absolute consistency' rule, gravitational-wave validation of the area theorem forces negative entropy corrections, which restricts F(R) gravity and would rule out two axions or an axion plus a graviton.
