Common Fixed Points of Kannan and Chatterjea Types of Mappings in a Complete Metric Space

This paper contains several generalizations of the theorems for common fixed point of R. Kannan, S. K. Chatterjea and P. V. Koparde & B. B. Waghmode types of mappings. These generalizations are done by using a sequentially convergent mappings. Trough several examples, we have shown that the generalized claims are inapplicable, and that the obtained generalized claims prove the existence of a unique common fixed point of considered mappings.
