AbstractIn this paper we prove a quasi-metric version of Ekeland Variational Principle and study its connections with the completeness properties of the underlying quasi-metric space. The equivalence with Caristi–Kirkʼs fixed point theorem and a proof of Clarkeʼs fixed point theorem for directional contractions within this framework are also considered
