ABSTRACT

Akdag and Ozkan pointed out in [1, Example 1] that the collection τ of soft sets is a soft topology over the universe X = {x1, x2, x3} where E = {e1, e2, e3} is the set of parameters. This conclusion is not correct since (F2,E)∩~(F7,E)∉τ, (F3,E)∪~(F8,E)∉τ, (F1,E)∪~(F13,E)∉τ, (F1,E)∩~(F13,E)∉τ, (F2,E)∩~(F13,E)∩~(F13,E)∉τ, (F2,E)∪~(F13,E)∉τ, (F2,E)∩~(F14,E)∉τ, and many of soft sets belong to the family  τ  and their soft intersection and soft union do not exist in τ. Consequently, [1, Examples 27, 28, 29, 30] also are incorrect. Example  3.3 in [2] already proved the results in [1, Remark 12] and [2, Examples 4.3 and 4.4] also proved the results in [1, Remark 26].
