设A是线性空间E的一个线性无关子集,A的基数(势)称为E的维数,记为dimE。当dimE< +∞时,称E为有限维的。否则称E为无限维的。
本文阐述了有限维与无限维线性空间的主要差别。
In this paper, we expound a main distinction between finite dimensional space and infinite dimensional space.
本文引入实无限维线性空间中的较多锥和严格较多锥,利用它们定义较多序,讨论较多序的性质,由此得出,实无限维线性空间中的任何两个元素都可以按较多序进行比较。
In this paper the major cone and the strict major cone in real infinite-dimensional linear space is introduced, through which we define the major-order, and their properties are also discussed.
