The Relevance of the Cosmological Constant for Lensing
Abstract
This review surveys some recent developments concerning the effect of the cosmological constant on the bending of light by a spherical mass in Kottler (Schwarzchild-de Sitter) spacetime. Some proposals of how such an effect may be put into a setting of gravitational lensing in cosmology are also discussed. The picture that emerges from this review is that it seems fair to assert that the contribution of to the bending of light has by now been well established, while putting the light-bending terms into a cosmological context is still subject to some interpretation and requires further work and clarification.
