One-sided approximation of sets of finite perimeter
Summary: In this note we present a new proof of a one-sided approximation of sets of finite perimeter introduced in [\textit{G.-Q. Chen} et al., Commun. Pure Appl. Math. 62, No. 2, 242--304 (2009; Zbl 1158.35062)], in order to fill a gap in the original proof.
