Cosmological consequences of an inhomogeneous space-time
F. Canfora, A. Troisi
Astrophysical observations provide a picture of the universe as a 4-dim homogeneous and isotropic flat space-time dominated by an unknown form of dark energy. To achieve such a cos…
Vacuum solutions which cannot be written in diagonal form
F. Canfora, H. -J. Schmidt
A vacuum solution of the Einstein gravitational field equation is given that follows from a general ansatz but fails to follow from it if a certain symmetric matrix is assumed to b…
Trace anomaly and black holes evaporation
F. Canfora, G. Vilasi
A model is proposed to describe a transition from a Schwarzschild black hole of mass to a Schwarzschild black hole of mass . The basic equations are der…
Spin-1 gravitational waves and their natural sources
F. Canfora, G. Vilasi
Non-vacuum exact gravitational waves invariant for a non Abelian two-dimensional Lie algebra generated by two Killing fields whose commutator is of light type, are described. The p…
