γ and β Approximations via General Ordered Topological Spaces ()
ABSTRACT
In this paper, we introduce the concepts of g and b approximations via general ordered topological approximation
spaces. Also, increasing (decreasing) g, b boundary,
positive and negative regions are given in general ordered topological
approximation spaces (GOTAS, for short). Some important properties of them were
investigated. From this study, we can say that studying any properties of rough
set concepts via GOTAS is a generalization of Pawlak approximation spaces and
general approximation spaces.
