In this paper, some new versions of coincidence point theorems and minimization theorems for single-valued and multi-valued mappings in generating spaces of the quasi-metric family are obtained. As applications, we utilize our main theorems to prove coincidence point theorems, fixed point theorems a

By following the approaches of Kada et al. [13], we define a family of weak quasi-metrics in a generating space of quasimetric family. By using a family of weak quasi-metrics, we prove a Takahashi-type minimization theorem, a generalized Ekeland variational principle and a general Caristi-type fixed
We obtain ΓΏxed point theorems for fuzzy mappings in Smyth-complete and left K-complete quasi-metric spaces, respectively. Well-known theorems are special cases of our results.
In the present work, we prove a coupled fixed point theorem for contractive mappings in complete fuzzy metric spaces.
