Solomon's descent algebra is generated by sums of descent classes corresponding to certain hook shapes. This particularly implies that the ring of class functions of any finite symmetric group S n is generated by the irreducible characters corresponding to certain hook partitions of n. As another co

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
