论文摘要
在这篇非常简短的论文中,我们为研究以下问题提供了强大的动机:鉴于一个真实的规范空间$ e $,一个封闭,凸,无限制的$ x \ subseteq e $和函数$ f:x \ to x $,找到合适的条件,在x $中,每个$ y \ in x $ in x $ y y y y y y y函数$ x \ y \ y \ y |最低$ x $。
In this very short paper, we provide a strong motivation for the study of the following problem: given a real normed space $E$, a closed, convex, unbounded set $X\subseteq E$ and a function $f:X\to X$, find suitable conditions under which, for each $y\in X$, the function $$x\to \|x-f(x)\|-\|y-f(x)\|$$ has at most one global minimum in $X$.
