Relativistic diffusing particles, entropy and varying cosmological constants

Z. Haba

We discuss Einstein equations with a non-conserved energy-momentum $T^{μν}$ . The energy-momentum tensor $T ~^{μν}$ on the right hand side of Einstein equations is expressed i…

Varying Newton constant, entropy and the black hole evaporation law

Julia Haba, Zbigniew Haba

In Einstein equations we represent the energy-momentum tensor as the one ( $T^{μν}$ ) of a fluid plus the cosmological term. We consider time-dependent Newton ``constant" $G$ , the c…
