On the Weak Form of Ekeland's Variational Principle in Quasi-Metric Spaces
(Elsevier, 2015) Karapinar, Erdal; Romaguera, Salvador
We show that a quasi-metric space is right K-sequentially complete if and only if it satisfies the property of the weak form of Eke land's Variational Principle. This result solves a question raised by S. Cobzas (2011) [3]. (C) 2015 Elsevier B.V. All rights reserved.

Matkowski Theorems in the Context of Quasi-Metric Spaces and Consequences on g-metric Spaces
(Sciendo, 2016) Karapinar, Erdal; Roldan-Lopez-de-Hierro, Antonio-Francisco; Samet, Bessem
In this paper, we prove the characterization of a Matkowski's theorem in the setting of quasi-metric spaces. As a result, we observe that some recent fixed point results in the context of G-metric spaces are consequences of our main result.
