Common fixed point under contractive condition of Ciric's type on cone metric type spaces

The purpose of this article is to generalize common fixed point theorems under contractive condition of A dagger iriA double dagger's type on a cone metric type space. We give basic facts about cone metric type spaces, and we prove common fixed point theorems under contractive condition of A dagger iriA double dagger's type on a cone metric type space without assumption of normality for cone. As special cases we get the corresponding fixed point theorems on a cone metric space with respect to a solid cone. Obtained results in this article extend, generalize, and improve, well-known comparable results in the literature. 2000 Mathematics Subject Classification: 47H10; 54H25; 55M20.
