Coincidence and fixed point theorems for single-valued and multi-valued maps generalizing recent results of Suzuki and Kikkawa are obtained. Various applications, including the existence of common solutions of certain functional equations are presented.

β¦ Synopsis
In [N. Mizoguchi, W. Takahashi, Fixed point theorems for multi-valued mappings on complete metric spaces, J. Math. Anal. Appl. 141 (1989) 177-188] the authors gave a positive answer to the conjecture of S. Reich concerning the existence of fixed points of multi-valued mappings that satisfy certain contractive conditions. In this paper, we establish some results for multi-valued mappings that satisfy a generalized contractive condition in a way that it contains Mizoguchi's result as one of its special cases. In addition, our results not only improve the results of Kiran and Kamran [Q. Kiran, T. Kamran, Nadler's type principle with high order of convergence, Nonlinear Anal. TMA 69 (2008) 4106-4120] and some results of Agarwal et al. [R.P. Agarwal, Jewgeni Dshalalow, Donal O'Regan, Fixed point and homotopy results for generalized contractive maps of Reich type, Appl. Anal. 82 (4) (2003) 329-350] but also provide the high order of convergence of the iterative scheme and error bounds. As an application of our results, we obtain an existence result for a class of integral inclusions.

Recently, extending ΔiriΔ's quasi-contraction to a very general setting, Proinov [Petko D.

We utilize Proinov's contractive type hypotheses for a self-map of a metric space t
In this paper, the concept of a set-valued contractive mapping is considered by using the idea of a generalized distance, such as the Ο -distance, in metric spaces without using the concept of the Hausdorff metric. Furthermore, under some mild conditions, we provide the existence theorems for fixed-
