AI 中文摘要
我们为连续无处可微函数族(记为$\ND[0,1]$)建立了可数维扩展性质。具体而言,我们证明了$C[0,1]$中每个非零元素都无处可微的有限维子空间$F$,可扩展为具有相同性质的可数无限维子空间$G$。
英文摘要
We establish a countable-dimensional extension property for the family of continuous nowhere differentiable functions, which we denote by $\ND[0,1]$. More precisely, we prove that every finite-dimensional subspace $F\subset C[0,1]$ whose nonzero elements are nowhere differentiable can be extended to a countably infinite-dimensional subspace $G\subset C[0,1]$ with the same property.
