Jachymski, Jacek Common fixed point theorems for some families of maps. (English) Zbl 0811.54034 Indian J. Pure Appl. Math. 25, No. 9, 925-937 (1994). Let \(A, B, S, T : (X,d) \to (X,d)\) be four mappings. The author gives some metric conditions which imply that \(A\), \(B\), \(S\) and \(T\) have a unique common fixed point. Some fixed point theorems are given, too.
