摘要
探讨线性空间的子空间覆盖问题,利用无限集的基数揭示子空间的覆盖,并提出最小覆盖的概念,对有限维线性空间的最小覆盖进行了刻画.
Mainly discuss the problem that linear space is covered by its subspaces.Used the cardinality of infinite set to reveal the subspaces cover,proposed the concept of minimal cover,and described the minimal cover of finite dimensional linear space.
