Certain aspects of J-statistical supremum and J-statistical infimum of real-valued sequences

Over the last few years, numerous researchers have contributed significantly to summability theory by connecting various notions of convergence concepts of sequences. In this paper, we introduce the concepts of J-statistical supremum and J-statistical infimum of a real-valued sequence and study some fundamental features of the newly introduced notions.We also introduce the concept of J-statistical monotonicity and establish the condition under which an J-statistical monotonic sequence is J-statistical convergent. We end up giving a necessary and a sufficient condition for the J-statistical convergence of a real-valued sequence.
