Some properties of s(Λ, sp)-open sets, p(Λ, sp)-open sets, α(Λ, sp)-open sets, β(Λ, sp)-open sets and b(Λ, sp)-open sets are discussed. In particular, the relationships between s(Λ, sp)-open sets, p(Λ, sp)-open sets, α(Λ, sp)-open sets, β(Λ, sp)-open sets, b(Λ, sp)-open sets and other related sets are established. Moreover, several characterizations of Λsp-extremally disconnected spaces are investigated.</p>}, number={2}, journal={European Journal of Pure and Applied Mathematics}, author={Boonpok, Chawalit and Khampakdee, Jeeranunt}, year={2022}, month={Apr.}, pages={572–588} }
