Stability of Jungck-type iterative procedures. (English) Zbl 1117.26005
The stability of Jungck(-Mann) iterative procedure on metric spaces is studied. The main theorems generalize and unify results by A. M. Harder and T. L. Hicks [Math. Jap. 33, No. 5, 687–692 (1988; Zbl 0655.47046) and ibid. 33, No. 5, 693–706 (1988; Zbl 0655.47045)], and by B. E. Rhoades [Indian J. Pure Appl. Math. 21, No. 1, 1–9 (1990; Zbl 0692.54027) and ibid. 24, No. 11, 691–703 (1993; Zbl 0794.54048)].
