Black hole motion in Euclidean space as a diffusion process II
K. Ropotenko
A diffusion equation approach to black hole thermodynamics in Euclidean sector is proposed. A diffusion equation for a generic in Euclidean sector is derived from the Bloch equatio…
Black hole motion in Euclidean space as a diffusion process
Kostiantyn Ropotenko
A diffusion equation for a black hole is derived from the Bunster-Carlip equations. Its solution has the standard form of a Gaussian distribution. The second moment of the distribu…
Quantization of the black hole area as quantization of the angular momentum component
Kostyantyn Ropotenko
In transforming from Schwarzschild to Euclidean Rindler coordinates the Schwarzschild time transforms to a periodic angle. As is well-known, this allows one to introduce the Hawkin…
Kolmogorov-Sinai entropy and black holes
Kostyantyn Ropotenko
It is shown that stringy matter near the event horizon of a Schwarzschild black hole exhibits chaotic behavior (the spreading effect) which can be characterized by the Kolmogorov-S…
A note on vacuum energy from the de Sitter spectrum
K. Ropotenko
It is shown that a well-known relation between entropy of a system and its energy spectrum being applied to the early universe determines the present vacuum energy and the time sca…
