iajs-477	Dawood, Narjis. A.U.	On Semi-p-Proper Mappings	2017	8	.pdf	application/pdf	3299	189	83	If A is a nonempty subset of X, and B a non empty subset of Y then: (1) If A is pre-closed subset of X and B is pre-closed subset of Y then A×B is pre-closed subset of X×Y. (2) If A is a semi-p-closed subset of X and B is a semi-p-closed subset of Y then A×B is semi-p-closed subset of X×Y. Proof: The proofs of parts (1) and (2) are similar, so we prove part (2) because our work about semi-p-closed sets. In this section we shall recall some needed definitions, propositions, and properties of semi-p-open sets and pre-open sets which we shall use to define semi-p-proper mapping, some of these propositions or definition are given for the first time by the author.	cache/iajs-477.pdf	txt/iajs-477.txt
