报告摘要：Let $E$ be a metric space, and let $K$ be a subset of $E$. By a $\textit{projection}$ from $E$ onto $K$ we mean a mapping $P$ from $E$ onto $K$ such that $Px=x$ for all $x\in K$. In this talk, we shall be interested in the existence of "uniformly continuous" projection on some special class of subsets in Banach spaces, called "super weakly compact sets". The class of subsets can be viewed as a localized notion of a super reflexive Banach space and has recently been studied by many researchers.
