A convergence theorem for Jungck-Ishikawa iteration

The theory of stability of iterative procedures plays an important role in the study of numerical computations. The revolution in the computational mathematics through computer programming has accelerated the increasing interest in the stability theory of iterative procedures. The purpose of this paper is to discuss the convergence of the Jungck-Ishikawa iteration scheme in the settings of b metric spaces. A recent result is also obtained as a special case.
