In this paper, we introduce some new classes of generalized mappings and prove some common fixed point theorems for a pair of asymptotically regular mappings. Our results extend and improve various well-known results due to Kannan, Reich, Wong, Hardy and Rogers, 'Ciri'c, Jungck, G'ornicki and many others. In addition to it, a sequential fixed point for a mapping which is the point-wise limit of a sequence of functions satisfying 'Ciri'c-Proinov-G'ornicki type mapping has been proved. Supporting examples have been given in strengthening hypotheses of our established theorems.
Keywords: Fixed point, common fixed point, asymptotic regularity, orbital continuity, $k$-continuity, 'Ciri'c-Proinov-G'ornicki type mapping
