ECTL is an extension of the computation tree logic (CTL) with two operators ∃GF and ∀FG where ∃GFϕand ∀FGψrepresent ‘there is a path along whichϕholds infinitely often’ and ‘along any path, there exists a state after whichψalways holds’, respectively. A Hilbert-style axiomatization of ECTL is defined by adding the schemata ∀G(ϕ→ψ) → (∃GFϕ→ ∃GFψ), ∃GFϕ↔ ∃F(ϕ∧ ∃X∃GFϕ), ∀G(ϕ→ ∃X∃Fψ) → (ψ→ ∃GFϕ) and ∀FGϕ↔ ¬ ∃GF¬ϕto the axioms of CTL. We prove its soundness and completeness with respect to arbitrary and finite models, i.e. equivalence of the following three conditions: (i)ϕis provable in this axiomatization of ECTL; (ii)ϕis valid in any model; (iii)ϕis valid in any finite model.
