In this work, the concept of ζ-Open Set was introduced as a generalization open set. Where it is shown that (X, ) Topological Space.
 Also, we study -Interior, -Closure, Continuity Function. At last basics Properties them are given.
In a graph G = ( V , E ), two edges e 1 and 2 are said to have common edge if there exists an ∈ ) different from such that joins vertex of in . That is, 〈 〉 is either P 4 or K 3 A non-empty set D ⊆ open packing no The maximum cardinality the number denoted by ρ o ). this paper, we initiate study on parameter.
