(
Hikari Ltd.
, 2014 , Article)
Linear programming is one of the frequently applied tools in supply chain management. However, managers and decision makers may lack information about exact values of most of the parameters used in the optimization models. ...
Common fixed point theorems for two pairs of self-mappings in partial metric space using C-class functions on (ψ, ϕ)-contractive condition
(
International Scientific Research Publications
, 2018 , Article)
The purpose of this paper is to introduce common fixed point results for two pairs of weakly compatible self-mappings in
partial metric space using C-class functions on (ψ, ϕ)-contractive condition. Example and application ...
