Multifunction between Soft Topological Spaces

Soft \(b\)-continuous and soft \(b\)-irresolute multifunctions

“…(3) bcl(F, A) is a sb-closed set in X. Theorem 2.21. [10] Let F : S(X, E) → S(Y, K) be a soft multifunction Then, for soft sets (F, E), (G, E) and for a family of soft sets (G i , E) i∈I in the soft class S(X, E) the following are hold:…”

“…Theorem 2.22. [10] Let F : S(X, E) → S(Y, K) be a soft multifunction. Then, for soft sets (G, K), (H, K) in the soft class S(X, E) the following are hold:…”

“…Proposition 2.23. [10] Let (G i , K) be soft sets over Y for each i ∈ I. Then the follows are true for a soft multifunction F : (X, τ, E) → (Y, σ, K):…”

“…If (F, B) is an soft open set and (F, A) is a soft b-open set in X. Then (F, A) ∩(F, B) is a soft b-open set in X.Definition 2.17 [10]. Let S(X, E) and S(Y, K) be two soft classes.…”

Upper and Lower Soft Contra Continuous Multifunctions

“…Ça g  man and et al redefined the operations of the soft sets and constructed a uni-int decision making method by using these new operations [7]. Then Akda g  and Erol [3,11,12] introduced the concept of soft multifunction and studied their properties. Many researcher studied on soft set theory [6,9,10] etc.…”
