摘要
在本文中,我们介绍了强 b 上解析空间,并在其中证明了 Banach 和 Edelstein 的定点原理。此外,我们还证明了埃克兰德的变分原理,并推导出卡利斯蒂定点定理。此外,我们还引入了强 b 上变形线性空间,并在其中建立了布劳威尔和绍德的定点原理。作为应用,我们研究了积分方程和三阶边界值问题的解的存在性。
Strong b-Suprametric Spaces and Fixed Point Principles
In this paper, we introduce the strong b-suprametric spaces in which we prove the fixed point principles of Banach and Edelstein. Moreover, we prove a variational principle of Ekeland and deduce a Caristi fixed point theorem. Furthermore, we introduce the strong b-supranormed linear spaces in which we establish the fixed point principles of Brouwer and Schauder. As applications, we study the existence of solutions to an integral equation and to a third-order boundary value problem.
