We give the formulation of the gravitational lensing theory in the strong field limit for a Schwarzschild black hole as a counterpart to the weak field approach. It is possible to expand the full black hole lens equation to work a simple analytical theory that describes the physics in the strong field limit at a high accuracy degree. In this way, we derive compact and reliable mathematical formulae for the position of additional critical curves, relativistic images and their magnification, arising in this limit.

• Gravitational lensing in a non-uniform plasma (2010, background): “When the impact parameter is close to its critical value, corresponding to the capture of the photon by the black hole, the expression for the deflection angle is more complicated (Darwin 1959; Misner et al. 1973; Virbhadra & Ellis 2000; Bozza et al. 2001; Bisnovatyi-Kogan & Tsupko 2008).”
