New types of nearly open sets in topological spaces and their applications

In the current study, the idea of Sψφ-open sets is used to introduce some new types of nearly open sets in topological space, where ψ={θ,δ,τ} and φ={θ,δ,τ,α,a}, thereby illustrating some of their basic qualities and the links between them. Some characterizations, topological properties, mappings, and separation axioms of these new concepts are also presented.
