On scalar curvature rigidity of Vacuum Static Spaces [PDF]

open access: yesarXiv, 2014
In this paper we extend the local scalar curvature rigidity result in [6] to a small domain on general vacuum static spaces, which confirms the interesting dichotomy of local surjectivity and local rigidity about the scalar curvature in general in the light of the paper [10].

On the existence of compact scalar-flat Kähler surfaces [PDF]

open access: yesRendiconti di Matematica e delle Sue Applicazioni, 1995
A compact compler surface with non-trivial canonical bundle and a Kähler metric ofzero scalar curvature must be a ruled surface. It is also known that not every ruled surface can admit such extremal Kähler metrics.

Non-minimal two-loop inflation

open access: yesPhysics Letters B, 2015
We investigate the chaotic inflationary model using the two-loop effective potential of a self-interacting scalar field theory in curved spacetime. We use the potential which contains a non-minimal scalar curvature coupling and a quartic scalar self ...
