The aim of this paper is to introduce the concept of compatible mappings of type (R) in 2-metric spaces and to prove a coincidence point theorem and a fixed point theorem for compatible mappings of type (R) in 2-matric spaces.
IndroductionRohen Singh, M.R & Shambhu introduced the concept of compatible mappings of type (C) by combinging the definition of compatible mappings and compatible mapping of type (P) and later on it is renamed as compatible mappings of type (R) [9]. Later it is extensively developed by Rohen and many others. In the last decade a number of authors
Compatible Mappings of type (R)Here the concept of compatible mappings of type (R) is introduced in 2-metric spaces and shown that these mappings are equivalent to compatible mappings and compatible mappings of type (A) under some conditions . Now, we shall state some definitions .
