Higher order corrections to lensing parameters for extended gravitational lenses
Salvatore Capozziello, Virginia Re
We discuss the contribution to the characteristic lensing quantities, i.e. the deflection angle and Einstein radius, due to the higher order terms (e.g. the gravitomagnetic terms)…

Gravitational lensing potential reconstruction in quadruply imaged systems
V. F. Cardone, S. Capozziello, V. Re +1
We develop a semi - analytical method to reconstruct the lensing potential in quadruply imaged gravitational lens systems. Assuming that the potential belongs to a broad class of b…
