Variational Principles, Minimization Theorems, and Fixed-Point Theorems on Generalized Metric Spaces
J.S. Ume 《Journal of Optimization Theory and Applications》2003,118(3):619-633
In this paper, we prove a new minimization theorem by using the generalized Ekeland variational principle. We apply our minimization theorem to obtain some fixed-point theorems. Our results extend, improve, and unify many known results due to Kui, Ekeland, Takahashi, Caristi, iri, and others. 相似文献

In this paper we develop the Banach contraction principle and Kannan fixed point theorem on generalized cone metric spaces.We prove a version of Suzuki and Kannan type generalizations of fixed point theorems in generalized cone metric spaces. 相似文献
