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 ( $T^{I^¼ I^½}$ ) of a fluid plus the cosmological term. We consider time-dependent Newton ``constant" $G$ , the…

Chern-Simons States in $S O (1, n)$ Yang-Mills Gauge Theory of Quantum Gravity

Zbigniew Haba

We discuss a quantization of the Yang--Mills theory with an internal symmetry group $S O (1, n)$ treated as a unified theory of all interactions. In one-loop calculations, we show tha…

Chern-Simons "ground state" from the path integral

Z. Haba

We consider a path integral representation of the time evolution $exp (- \frac{i}{ℏ} t H)$ for Lagrangians of the variable $A$ which can be represented in the form (quadratic in $…
