Abstract

Molodstov[10] introduced soft set theory as a new mathematical approach for solving problems having uncertainties. Many researchers worked on the findings of structures of soft set theory and applied to many problems having uncertainties. Recently, Bin Chen [3-4] introduced and explored the properties of soft semi-open sets and soft-semi-closed sets in soft topological spaces. In this paper we continue to investigate the properties of soft semi-open and soft semi-closed sets in soft topological spaces. We define soft semi-exterior, soft semi-boundary, soft semi-open neighbourhood and soft semi-open neighbourhood systems in soft topological spaces. Moreover we discuss the characterizations and properties of soft semi-interior, soft semi-exterior, soft semi-closure and soft semi-boundary. We also develop the relationship between soft semi-clopen sets and soft semi-boundary. The addition of this topic in literature will strengthen the theoretical base for further applications of soft topology in decision analysis and information systems.

A Theory of Scales and Orbit Covers

This paper develops a formal theory of musical scales and their harmonic coverings and introduces orbit covers: coverings obtained by translating a fixed subset across a scale via a group action. Orbit covers generalize familiar constructions, such as the covering of the diatonic scale by tertian triads, and are motivated by the search for a generalized harmonic framework extending common-practice tonality. We model modes as group structures associated with pitch-class sets and scales as torsors, introducing scale covers and, in particular, orbit covers. To each orbit cover we associate a nerve complex encoding its intersection structure and associated topological invariants. We classify triadic orbit covers of heptatonic scales up to affine symmetry and nerve isomorphism. These results support a broader theory of harmonic organization with analytical and compositional applications.
