Neutrosophic Φ-open sets and neutrosophic Φ-continuous functions

We introduce the notion of neutrosophic Φ -open set and neutrosophic Φ -continuous
mapping via neutrosophic topological spaces and investigate several properties of it. By defining
neutrosophic Φ -open set, neutrosophic Φ -continuous mapping, and neutrosophic Φ -open
mapping, we prove some remarks, theorems on neutrosophic topological spaces.
