A generalization of Banach's contraction principle for some non-obviously contractive operators in a cone metric space

This paper investigates the fixed points for self-maps of a closed set in a space of abstract continuous functions. Our main results essentially extend and generalize some fixed point theorems in cone metric spaces. An application to differential equations is given.

  • Then, by Theorem 3.1, we know Equation (4.1) has a nontrivial solution. This completes the proof. Remark 4.1 However, when √ +82π π−2 by Theorem 3.2 in [27] (see [27, Example 4.1]). Therefore, our results in this paper extend and improve them in [27].
