| Abstract | ||
| This work consists of three sections. In section one we will study the properties of P-connected spaces [3] and we will show that the product of two P-connected spaces is Pconnected. In section two we recall the definition of I- space [2] and we will introduce similar definition PI-space using pre open sets and also we will study some properties of this definition. In [8],[2] D T -space and MI- space are studied respectively. In section three we introduce similar definition P T - space using pre open sets. In particular we will prove that in MI-space the P T - space and D T -space are equivalent. | ||
