摘要:On the basis of the theory of a falling shadow which was first formulated by Wang (1985), the notion of falling 𝑑∗-ideals in 𝑑-algebras is introduced, and related properties are investigated. Characterizations of a falling 𝑑∗-ideal are established. Relations among falling 𝑑∗-ideals, falling 𝑑-ideals, falling 𝑑#-ideals, falling 𝑑-subalgebras, and falling BCK-ideals are discussed.
