On the convex components of a set in ${\mathbb{R}}^n$

Abstract

We prove a lower bound on the number of the convex components of a compact set with non-empty interior in ${\mathbb{R}}^n$ for all $n\ge 2$. Our result generalizes and improves the inequalities previously obtained in M. Carozza, F. Giannetti, F. Leonetti and A. Passarelli di Napoli, "Convex components", in Communications in Contemporary Mathematics, Vol. 21, No. 06, 1850036 (2019) and in M. La Civita and F. Leonetti, "Convex components of a set and the measure of its boundary", Atti. Sem. Mat. Fis. Univ. Modena Reggio Emilia 56 (2008-2009) 71-78.
