Quantum Effects of Scalar Fields in Black Hole and Cosmological Spacetimes
… of a cosmological spacetime containing a big rip singularity. The spacetime investigated is that of a spatially flat FRW metric in which the scale factor increases as a power-law with a divergence at some future time $t=t_{\text{rip}}$. Results of analytical and numerical computations of …

THE COVARIANT APPROACH TO SPACE TIMES ANDSOME EXTENDED THEORIES OF GRAVITY
The thesis deals with the covariant description of the geometry of some fundamental spacetimes and their realizations in two recent extensions of GR: Cotton and conformal Killing gravity. In Generalized Robertson - Walker spacetimes the Ricci tensor is the sum of a perfect fluid term and an …
