| Outline of Final Research Achievements |
In these three years, we have several results in nonlinear problems related to fixed point theory. For example, we have introduced new classes of nonlinear mappings (Chatterjea mapping, Condition (CC)) and studied basic properties, existence of fixed points and convergence theorems. We have given examples of nu-generalized metric spaces that do not have the compatible topology. Also we have proved that every 3-generalized metric space has the compatible topology. We have obtained a new sufficient and necessary condition for successive approximation.
