Quantum Regular Black Holes and Complete Monotonicity

We examine the conjecture for the complete monotonicity of certain curvature invariants for quantum black holes. In this note, we study a class of quantum regular black holes that are static, spherically symmetric, and characterized only by their mass. Additionally, this class of black holes reduces to the Schwarzschild solution in the classical limit $\hbar\to 0$. We provide evidence supporting the non-perturbativity conjecture that perturbative corrections cannot falsify complete monotonicity. We demonstrate that these quantum black holes cannot be generated by perturbative quantum corrections to the Einstein equations. We then investigate the thermodynamics of these black holes and derive a bound on their entropy, showing that the entropy is always greater than the horizon area divided by 4G. We Also demonstrate that these black holes exhibit a bounded temperature, with a maximum temperature scaling as $T\sim\frac{1}{L_p}$ and a critical mass scale where the temperature vanishes
