Coincidence and common fixed points for hybrid strict contractions without the weakly commuting condition. (English) Zbl 1225.54028
Summary: We establish new coincidence and common fixed point theorems for hybrid strict contraction maps by dropping the assumption “\(f\) is \(T\)-weakly commuting” for a hybrid pair \((f,T)\) of multivalued maps in Theorem 3.10 of T. Kamran [J. Math. Anal. Appl. 299, No. 1, 235–241 (2004; Zbl 1064.54055)]. As an application, an invariant approximation result is derived.
