Some Caristi type fixed point theorems
Aslantas, Mustafa; Sahin, Hakan; Turkoglu, Duran (Springernature, 2021)In 1976, Caristi fixed point theorem was proved for ordinary metric spaces. After that, it was shown that this result is equivalent to Ekeland variational principle which has a great number of applications in many branches ... -
Some Ciric Type Periodic Point Results with Q-function on Quasi Metric Spaces
Sahin, Hakan; Turkoglu, Duran (Amer Inst Physics, 2021)In this paper, we proved a Ciric type periodic point result with a Q-function on quasi metric spaces. We also give an illustrative example to show the effectiveness of our main result.
