原始语种摘要: Summary: We introduce a new class of sets, namely the class of $\delta$-generalized semi-closed (briefly $\delta$-gs-closed) sets by generalizing open sets via $\delta$-semi-closure. This class is properly placed between the classes of $\delta$-sg-closed sets and gs-closed sets. The class of $\delta$-gs-closed sets properly contains the class of $\delta$-semi-closed sets, and thus it contains the class of $\delta$-closed sets. This class is properly contained in the class of gsp-closed sets. The class of $\delta$-gs-closed sets is independent of the classes of closed sets, $\alpha$-closed sets, semi-closed sets, $\psi$-closed sets, semi-preclosed sets, preclosed sets, g-closed sets, sg-closed sets, $\delta$-preclosed sets and the class of $\delta$-g-closed sets.
