On the convergence of the Ishikawa iterates associated with a pair of multi-valued mappings (Q1416120)

Let \(S\) and \(T\) be multivalued maps satisfying the condition \[ H(Sx,Ty) \leq ad (x,y)+q\max\{D(x,Sx) + D(y,Ty),D(x,Ty)+D(y,Sx)\} \] for some \(a\in (0,\infty)\) and \(q\in(0,1)\). The authors study the convergence of the Ishikawa iterators for \(S\) and \(T\).
