上下联说的基本上是对的(不考虑直线不相交、点重合等各种特殊情况)。 这两句话其实就是一个“对偶”,我猜测“对偶”这个词取名就来自于和中国诗歌、对联的类比(没找到“对偶”这个词的来历)。 1 对偶的历史 1.1 出现 18、19世纪的数学研究者发现,涉及平面图形的定理如果把“点”换成“线”、“线”换成“点...

dual vector space 英 [ˈdjuːəl ˈvektə(r) speɪs] 美 [ˈduːəl ˈvektər speɪs]网络 对偶向量空间
在数学里，任何向量空间V都有其对应的对偶向量空间（或简称为对偶空间），由V的线性泛函组成。此对偶空间俱有一般向量空间的结构，像是向量加法及标量乘法。由此定义的对偶空间也可称之为代数对偶空间。在拓扑向量空间的情况下，由连续的线性泛函组成的对偶空间则称之为连续对偶空间。对偶空间是行向量（1...
For a vector measure ν having values in a real or complex Banach space and \\\({p \\\in}\\\) [1, ∞), we consider L p ( ν ) and \\\({L_{w}^{p}(u)}\\\) , the corresponding spaces of p -integrable and scalarly p -integrable functions. Given μ , a Rybakov ...

This paper proposes a dual-space vector control scheme for the open-end winding permanent magnet synchronous motor (OEW-PMSM) drive fed by the dual inverter with a single dc supply. Potential zero-sequence current in the open-end winding drive system has to be considered since it causes circul...
The space of Boehmians with "-convergence is a complete topological vector space in which the topology is induced by an invariant metric. We show that the dual space of the space of periodic Boehmians can be identified with the class of trigonometric polynomials....
A space vector PWM technique is developed based on the combination of space vectors from dual inverters feeding the induction motor from both ends (open-end winding without neutral point). A total of 64 voltage space vector combinations are available for PWM voltage control of the inverter fed ...
