A pair of non-self mappings in cone metric spaces

Stojan Radenović

In this paper we extend from metric to cone metric spaces a fixed point theorem for a pair of non-self maps proved by M. S. Khan et al. [M. S. Khan, K. Pathak and M. D. Khan, Some fixed point theorems in metrically convex spaces, Gregorian Mathematical Journal, Volume {\bf 7} (3) (2000), 523-530].
