C-class functions and pair (f , h) upper class on common best proximity points results for new proximal c-contraction mappings
A H Ansari, Geno Kadwin Jacob, D Chellapillai
In this paper, using the concept of C−class and Upper class functions we prove the existence of unique common best proximity point. Our main result generalizes results of Kumam et al. [[17]] and Parvaneh et al. [[21]].
