I think the affirmative answers are for the questions 1), 3). But about the remaining questions I can't tell anything. I am not sure, but I think 4) is affirmative, also--but I'm not sure. Thanks :) linear-algebra vector-spaces Share Cite Follow edited Dec 4, 2012 at 11:02...
linear algebra的核心就是向量的两种操作:addition和scalar multiplication。使用这两种操作就可以产生一个“linear combination”。例如,有两个向量v和u,通过addition可以得到向量v+u,再给v和u分别乘上一个scalar c和d,可以得到cv+du,这就是一个linear combination cv+du Subspaces spanned by a set 一个空间有无...
Your exercise is from Halmos: Finite-Dimensional Vector Spaces. If VV is a vector space, y∈V′y∈V′ (the dual space of V)V) and x∈Vx∈V, the notation [x,y][x,y] stands for the scalar y(x)y(x), which one obtains when one inserts xx into yy. It is explained in the te...
Elements ofFare called scalars.The words "scalar",a fancy word for "number",is often used when we want to emphasize that an object is a number,as opposed to a vector(vectors will be difined soon). Forα∈Fandma positive integer,we defineαmto denote to denote the product ofα...

The reader will undoubtedly have met most of the concepts in connection with vectors in ordinary three-dimensional space and probably also in a standard first course on linear algebra and matrices. To many, therefore, this chapter will be revision, but it should not be treated too lightly ...

首先，我们来介绍复数，一个有序对 (a, b)，其中 a, b 属于实数集 R，形式为 a + bi，其中 i 表示虚数单位，满足 i^2 = -1。复数集 C 包含所有形式为 a + bi 的复数。复数集 C 是实数集 R 的一个子集，对于任意实数 a，都可以用形式 a + 0i 表示。复数的运算遵循特定的性质，...
