This paper employs an order-theoretic framework to explore the intricacies of formal concepts. Initially, we establish a natural correspondence among formal contexts, preorders, and the resulting partially ordered sets (posets). Leveraging this found

In this paper, we give two weak conditions for a lower semi-continuous function on the n-dimensional Euclidean space Rn to be a convex function. We also present some results for convex functions, strictly convex functions, and quasi-convex functions.

We present variable precision generalized rough set approach to characterize incomplete decision tables. We show how to determine the discernibility threshold for a reflexive relational decision system in the variable precision generalized rough set

In this paper, we propose a definition of system-consistent (sys-consistent) functions for neighborhood systems and compare it with a previous definition of granule-based consistent (gra-consistent) functions in the literature. We show that sys-consi

In this paper, we provide a definition of α-fuzzified lower and upper approximations for fuzzy sets based on the α-cut of fuzzy binary relations. We show that the definition is a proper generalization of the previous one for approximations of crisp

Using the concepts of category and functor, we provide some insights and prove an intrinsic property of the category AprS of approximation spaces and relation-preserving functions, the category RCls of rough closure spaces and continuous functions, a
