In this paper a generalized notion of an approximation space is considered. By an approximation space we mean an ordered pair \((U, \mathbb{C})\), where \(U\) is a finite nonempty set and \(\mathbb{C}\) is a covering of \(U\). According to connections between rough sets and concepts we define two ty

## Abstract We consider the sets definable in the countable models of a weakly o‐minimal theory __T__ of totally ordered structures. We investigate under which conditions their Boolean algebras are isomorphic (hence __T__ is p‐__Ο‰__‐categorical), in other words when each of these definable sets adm
