A scalar hyperbolic equation with GR-type non-linearity
A. M. Khokhlov, I. D. Novikov
We study a scalar hyperbolic partial differential equation with non-linear terms similar to those of the equations of general relativity. The equation has a number of non-trivial a…

Slim accretion discs: a model for ADAF-SLE transitions
I. V. Igumenshchev, M. A. Abramowicz, I. D. Novikov
We numerically construct slim, global, vertically integrated models of optically thin, transonic accretion discs around black holes, assuming a regularity condition at the sonic ra…

Dynamical Origin of the Entropy of a Black Hole
Valery Frolov, Igor Novikov
Modes of physical fields which are located inside a horizon and which cannot be observed by a distant observer are identified with dynamical degrees of freedom of a black hole. A n…
