Weak Gravitational Lensing in Fourth Order Gravity

A. Stabile, An. Stabile

For a general class of analytic $f(R,R_{\alpha \beta }{R}^{\alpha \beta },R_{\alpha \beta \gamma \delta }{R}^{\alpha \beta \gamma \delta })$ we discuss the gravitational lensing in the Newtonian Limit of theory. From the properties of Gauss Bonnet inva…
