Effective delta sources and regularity in higher-derivative and ghost-free gravity
Breno L. Giacchini, Tibério de Paula Netto
It is shown that polynomial gravity theories with more than four derivatives in each scalar and tensor sectors have a regular weak-field limit, without curvature singularities. Thi…

Weak-field limit and regular solutions in polynomial higher-derivative gravities
Breno L. Giacchini, Tibério de Paula Netto
In the present work we show that, in the linear regime, gravity theories with more than four derivatives can have remarkable regularity properties if compared to their fourth-order…

Light bending in extended gravity theories
Breno L. Giacchini, Ilya L. Shapiro
We show that in the weak field limit the light deflection alone cannot distinguish between different models of gravity, where and are arbitrary functio…
