Instead, it has been recently proposed to make $r=0$ a regular center by properly modifying the metric, still preserving its form in regions far from $r=0$. Different algorithms of such modifications have been formulated for a few classes of singularities. The p","authors_text":"K.A. Bronnikov, M.V. Skvortsova, S.V.
