Pair of non-self-mappings and common fixed points

We study quasi-contraction type non-self-mappings on Takahashi convex metric spaces and common fixed point theorems for a pair of maps. Results generalizing and unifying fixed point theorems of Imdad and Kumar, Das and Naik, Jungck, Ćirić, Ume, Khan and Pathak, and Ćirić are established.
