Contribution of the cosmological constant to the relativistic bending of light revisited
Contribution of the cosmological constant to the relativistic bending of light revisited
We study the effect of the cosmological constant $\ensuremath{\Lambda}$ on the bending of light by a concentrated spherically symmetric mass. Contrarily to previous claims, we show that, when the Schwarzschild-de Sitter geometry is taken into account, $\ensuremath{\Lambda}$ does indeed contribute to the bending.
