On δp-homeomorphic topological structures and δp*- homeomorphic topological structures

In this thesis properties of δ-pre-irresolute functions, δ-preclosed functions andδ-preopen functions, δ-almost continuous functions, weak δ-preopen functions andweak δ-preclosed functions had been researched. δp-homeomorphisms with δp-δp*-homeomorphisms δp*-homeomorphic topological structures and withhomeomorphic topological structures that being formed by using these functions hadbeen introduced and their properties and preservation theorems had been researched.Keysword : δ-pre-irresolute function, δ-preclosed function, δ-preopen function, δ-almost continuous function, weak δ-preopen function, weak δ-preclosed function, δp-homeomorphism, δp*-homeomorphism.The present M.
