Common fixed point theorems for expansion mappings in various spaces

We prove expansion mappings theorems in various spaces i.e., metric spaces, generalized metric spaces, probabilistic metric spaces and fuzzy metric spaces, which generalize the results of various authors like Daffer and Kaneko 11], Ahmad, Ashraf and Rhoades 1], Vasuki 38], Rhoades 31] and Wang, Li, Gao and Iseki 40] etc. In the memory of 65^th birthday anniversary of his Father Late Sh.
