Abstract :We obtain quasi-metric versions of Kannan's fixed point theorem for self-mappings and multivalued mappings, respectively, which are used to deduce characterizations of d-sequentially complete and of left K-sequentially complete quasi-metric spaces, respectively.Keywords : Quasi-metric space, complete, Kannan mapping, fixed point
