Boosted Horizon of a Boosted Space-Time Geometry
Emmanuele Battista, Giampiero Esposito, Paolo Scudellaro +1
We apply the ultrarelativistic boosting procedure to map the metric of Schwarzschild-de Sitter spacetime into a metric describing de Sitter spacetime plus a shock-wave singularity…
Riemann curvature of a boosted spacetime geometry
Emmanuele Battista, Giampiero Esposito, Paolo Scudellaro +1
The ultrarelativistic boosting procedure had been applied in the literature to map the metric of Schwarzschild-de Sitter spacetime into a metric describing de Sitter spacetime plus…
On the transition from complex to real scalar fields in modern cosmology
Giampiero Esposito, Raju Roychowdhury, Claudio Rubano +1
We study some problems arising from the introduction of a complex scalar field in cosmology, modelling its possible behaviors in both the inflationary and dark energy stages of the…
