In this paper, we introduce the concept of a Q-function defined on a quasi-metric space which generalizes the notion of a ฯ -function and a w-distance. We establish Ekeland-type variational principles in the setting of quasi-metric spaces with a Q-function. We also present an equilibrium version of
