This paper contains some common fixed point theorems in metric spaces. The main result can be stated as follows: Theorem: Let , , and be mappings from a complete metric space into itself satisfying the conditions: (i) and ,
for all , in , where . Further, suppose that (iii) one of , , and is continuous, (iv) pairs , and , are compatible on . Then , , and have a unique common fixed point in . The above theorem generalizes several known results due to B. Fisher, G. Jungck, M. S. Khan and M. Imdad. A result for compact metric space is also proved. Examples are given to illustrate all the results.
