Abstract
In this paper we introduce a class of one dimensional non-centered minimal operator \({\widetilde{m}}_\Phi \) associated to a function \(\Phi \), which covers the usual minimal operator. We establish the boundedness of \({\widetilde{m}}_\Phi :\textrm{BV}(\mathbb {R})\rightarrow \textrm{BV}(\mathbb {R})\) under a more restrictive condition on \(\Phi \). Here \(\textrm{BV}(\mathbb {R})\) is the set of functions of bounded variation defined on \(\mathbb {R}\). In the discrete setting, we prove the discrete minimal operator is bounded and continuous from \(\textrm{BV}(\mathbb {Z})\) to itself under a more restrictive condition on \(\Phi \).
