unique common fixed point results in c*-algebra valued metric spaces using (φ-c∗)-contractions of hardy-rogers type

In this paper we have developed c lowast; -class function and introduced ( phi;-c lowast;)-contractions of hardy-rogers type on c lowast;-algebra valued metric spaces.we have also established some unique common fixed point results for six maps in c lowast;-algebra valued metric spaces using this type contractions. some basic definitions, proper-ties and lemmas are also discussed in the introduction and prelim-inaries parts. some corollaries and examples are also given on the basis of the results.
