The 'absolute stiff' matter ($P=E$) can be a Fermi or Bose gas of particles with the energy spectrum $\epsilon_p \sim p^q$ in $q$-dimensional space, particularly $\epsilon_p =p^3/m^2$ in 3-dimensional...
This thesis deals with the dynamics of irreversible processes within the context of the general theory of relativity. In particular, we address the problem of the 'infinite' speed of propagation of th...

We prove that the first law of black hole thermodynamics, $\delta Q=T\delta S$, is violated in $f(T)$ gravity. As a result, there always exists entropy production, which implies that the black hole th...

We consider the low-energy effective field theory describing the infrared dynamics of non-dissipative fluids. We extend previous work to accommodate conserved charges, and we clarify the matching betw...

We show that treating gravitation as a thermodynamical theory leads to the modified Newton dynamics (MOND) equations if one takes into account the Hubble's expansion. Then the universal MOND accelerat...
Towards a Holographic Description of Inflation and Generation of Fluctuations from Thermodynamics

Recently, Verlinde conjectured that gravity may be an entropic force, arising from thermodynamics on the holographic screen. We investigate the implications of the entropic force formalism for inflati...

We discuss three different corrections to the area law of entropy. The number of bits $N$ is then modified according to the form of entropy, and the law of gravity is obtained by using the method deve...
A SIMPLE, APPROXIMATE METHOD FOR ANALYSIS OF KERR-NEWMAN BLACK HOLE DYNAMICS AND THERMODYNAMICS

In this work we present a simple approximate method for analysis of the basic dynamical and thermodynamical characteristics of Kerr-Newman black hole. Instead of the complete dynamics of the black hol...
We propose a simple procedure for evaluating the main attributes
of a Schwarzschild's black hole: Bekenstein-Hawking entropy, Hawking temperature
and Bekenstein's quantization of the surface area. W...
