Prudhvi prudhvikasani@rocketmail.com 1 Department of Mathematics, University College of Science, Saifabad, Osmania University, Hyderabad, Telangana State, India In this paper, we prove a unique common fixed point theorem for weakly contractive three mappings in cone metric spaces. Our results generalize and extend some recent results in the literature. http://pubs.sciepub.com/ajams/3/4/5/ajams-3-4-5.pdf Fixed point common fixed point regular cone weakly compatible
