Ansari's method in generalizations of some results in the fixed point theory: Survey

Multi-valued fixed point theorem via F- contraction of Nadler type and application to functional and integral equations

“…Several researchers took after the idea of Czerwik and illustrated interesting results. For detail see ( [2], [8], [9], [10], [14], [15], [16]).…”

Some New Results on Equivalent Cauchy Sequences and Their Applications to Meir-Keeler Contraction in Partial Rectangular Metric Space

“…The partial metric space is a generalization of the usual metric spaces in which the distance of a point from itself may not be zero. In these spaces, related to the theory of fixed point many authors have given their contribution such as Došenović and Radenović [10], Radenović [11], Kirk and Shahzad [1].…”
