摘要：
In this talk we discuss some classical aspects of general polynomial higher-derivative gravity. In particular, we describe the behaviour of the weak-field solutions associated to a point-like mass at small distances and provide necessary and sufficient conditions for the metric to be regular. We also consider the metric for a collapsing thick null shell, and verify that it is regular if the aforementioned conditions are valid.
