We investigate various properties of these sets and we obtain new results. Moreover, we analyze the relationships between these sets and some special sets such as ΨΓ−C set and σ-open set in the literature. Additionally, we observe that the families of Γ−ΨΓ−sets and pre−Γ−ΨΓ− sets form a supratopology on W in the case cl(υ)∩I = {∅}.eninfo:eu-repo/semantics/openAccessLocal closure functionΨΓ − C setΓ − ΨΓ − setpre − Γ − ΨΓ − setArticle57661963110.52280/pujm.2025.57(06)01N/AWOS:001631635000001
