Erratum to: Strong Gravitational Lensing in a Brane-World Black Hole

Abstract

In this erratum to our published paper, we correct and clarify some of statements. A few equations given in our paper were in fact obtained and published many years ago by Virbhadra's research group. We clarify that those equations were neither obtained by us nor by other authors cited in our paper.(A) See a paragraph above Eq. 7. There is an equations in this paragraph which is not numbered. Here, we correct our statement and give reference. According to the geometric principle, the relationship between the image and the source can be described by the seminal Virbhadra-Ellis lens equation [1], which is(1) There are many gravitational lens equations, but this by Virbhadra and Ellis is most used because of its accuracy.(B) The Eq. 7 in our paper was obtained by Virbhadra et al. [2] and is also discussed in [3]. This equation is for light deflection angle in a general space-time (static and spherically symmetric).The online version of the original article can be found at http://dx
