Abstract


In this paper, we prove expansion mapping theorems in metric spaces the expansion  factor being controlled by a non-decreasing function using the concept of  compatible maps, weakly reciprocal continuity, R- weakly commuting of  type (A f ) and (P).


Keywords


Expansion mapping, φ- weakly expansive mapping, compatible mapping, R- weakly commuting mapping, expanding maps, expansion factor.
