Deflection of Light Based on the Kaluza–Klein Theory in the Presence of Decaying Dark Energy

Abstract

© 2018, Springer Science+Business Media, LLC, part of Springer Nature. For a proposed model of decaying dark energy the deflection of light in spherically-symmetric static Gross–Perry spacetime and in Kerr–Taub–Bolt spacetime is considered. Estimates are given for the variation of the standard deflection of light in the field of the Sun.
