摘要
In this paper we study common fixed points for the self and non-self (g,f) type maps in cone metric spaces. Our main results are related to the cases when g is f quasi contraction in a sense of Das and Naik, and the cone need not be normal. These results generalize several well known comparable results in the literature. (C) 2011 Elsevier Inc. All rights reserved.
