In this work we introduce and study a new class of open sets by means of preopen that we call Ip-open set. By the above mentioned set, several new concepts such as Ip-continuous functions, almost and weakly Ip-continuous functions, Ip-open and Ip-closed functions, Ip-connected and Ip-separation axioms are defined and studied. In the light of this work, some of our main results can be listed as follows: If a space (X, τ) is hyperconnected, then IpO(X) pO(X), and The following statements are equivalents for the function f: (X, τ) (R) (Y, σ): f is Ip-continuous, the inverse image of every open set in Y is Ip-open set in X, the inverse image of every closed set in Y is Ip-closed set in X, for each AÃX, f (Ipcl(A))Ã clf (A), for each AÃX, intf (A) Ã f (Ipint(A)), for each BÃY, Ipcl(f ˉÂ¹ (B))Ã f ˉÂ¹ (clB), for each BÃY and f ˉÂ¹ (intB)Ã Ipint(f ˉÂ¹ (B)). Moreover let f: (X, τ) --(Y, σ) be a function and let {A: } be pre-open cover of X. If the restriction fA: A Y is Ip-continuous function for each, then f is Ip-continuous function. and also a function f: (X, τ)--(Y, σ) is an Ip -open function if and only if for every BÃY, f ˉÂ¹ (Ip Cl (B)) Ã Clf ˉÂ¹ (B).
