Summary: A metrical common fixed point theorem proved for a pair of self mappings due to K. P. Sastry
and I. S. R. Murthy
[J. Math. Anal. Appl. 250, No. 2, 731–734 (2000; Zbl 0977.54037
)] is extended to symmetric spaces which in turn unifies certain fixed point theorems due to R. P. Pant
[J. Math. Anal. Appl. 240, No. 1, 280–283 (1999; Zbl 0933.54031
)] and S.-H. Cho
et al. [Fixed Point Theory Appl. 2008, Article ID 562130, 9 p. (2008; Zbl 1169.54020
)] besides deriving some related results. Some illustrative examples to highlight the realized improvements are also furnished.
