Abstract
The purpose of the present paper is to consider new classes of generalized compact spaces called Еc-(resp. δ-ßc)-compact spaces via Еc-(resp. δ-ßc)-open sets respectively. Several characterizations and fundamental properties concerning of these forms of spaces are obtained. Moreover, some new types of separation axioms in topological spaces namely Еc-(resp. δ-ßc)-separation axioms via Еc (resp. δ-ßc)-open sets are introduced and studied. Several of their fundamental properties and relationships with other well-known types of spaces are discussed.

Keywords
Еc-(resp. δ-ßc)-Compact space, Еc-(resp. δ-ßc)-open sets, Еc- separation axioms, δ-ßc- separation axioms.
