Weak-field limit and regular solutions in polynomial higher-derivative gravities
Abstract 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 counterpart. To this end, we derive the expressions for the metric potentials associated to a pointlike mass i...
