Description
Summary:Our paper is devoted to indicating a way of generalizing Mann&#8217;s iteration algorithm and a series of fixed point results in the framework of <i>b</i>-metric spaces. First, the concept of a convex <i>b</i>-metric space by means of a convex structure is introduced and Mann&#8217;s iteration algorithm is extended to this space. Next, by the help of Mann&#8217;s iteration scheme, strong convergence theorems for two types of contraction mappings in convex <i>b</i>-metric spaces are obtained. Some examples supporting our main results are also presented. Moreover, the problem of the <i>T</i>-stability of Mann&#8217;s iteration procedure for the above mappings in complete convex <i>b</i>-metric spaces is considered. As an application, we apply our main result to approximating the solution of the Fredholm linear integral equation.
