%0 Journal Article %T Unified implicit common fixed point theorems under non-negative complex valued functions satisfying the identity of indiscernible %A Singh, Deepak %A Joshi, Vishal %A Imdad, Mohammad %A Kumam, Poom %J Journal of Nonlinear Sciences and Applications %D 2016 %V 9 %N 5 %@ ISSN 2008-1901 %F Singh2016 %X In this paper, we consider a non-negative complex valued function satisfying the identity of indiscernible and utilize the same to prove some common fixed point theorems for two pairs of non-vacuously weakly compatible mappings satisfying an implicit relation having rational terms as its co-ordinates. Some illustrative examples are also given which demonstrate the validity of the hypotheses of our results. In process, a host of previously known results in the context of complex as well as real valued metric spaces are generalized and improved. %9 journal article %R 10.22436/jnsa.009.05.11 %U http://dx.doi.org/10.22436/jnsa.009.05.11 %P 2049--2069
