Abstract

In recent years, many researchers have made significant contributions to summability theory by linking various convergence concepts of sequences. In this work, we present the definitions of \(\mathfrak{I}_{2}\)-statistical supremum and \(\mathfrak{I}_{2}\)-statistical infimum for sequences, and investigate some of their key properties. Additionally, we introduce the concept of \(\mathfrak{I}_{2}\)-statistical monotonicity and establish the criteria under which an \(\mathfrak{I}_{2}\)-statistically monotonic sequence converges in the \(\mathfrak{I}_{2}\)-statistical sense. Ultimately, we provide both a necessary and a sufficient criterion for the \(\mathfrak{I}_{2}% \)-statistical convergence of a real-valued sequence.
