We introduce and discuss several types of ?-?-contractive mappings on quasi-metric spaces. We obtain some fixed point theorems in this setting and present suitable examples to show the validity of our approach and results. Finally, we give a characterization of doubly Hausdorff right K-sequentially complete quasi-metric spaces in terms of ?-?-contractive type mappings having fixed point.
