Some fixed point theorems in convex metric spaces

The concept of a convex metric space was introduced by Takahashi 10]. He observed that it is possible to generalize fixed point theorems in Banach spaces. Subsequently, Machado 8], Itoh 5], Naimpally, Singh and Whitfield 9] and Beg and Azam 2], among others have studied fixed point theorems in convex metric spaces. This paper is a continuation of these investigations.
