线性子空间的定义就必须保证它自己是一个线性空间。
两个答案解法都没错。子空间当然是向量空间，因为对线性运算封闭并继承了原空间（题目中是R3）的8条运...
Note that in an inner product space, there is a convenient expression for a given vector, v, in terms of some orthonormal basis, {en}, as: v=∑n〈en,v〉en. 7.1.5 Subspaces A subset, W, of a vector space, V, is a subspace if it is a vector space in its own right, under ...

In this paper, the authors introduce a graph structure, called subspace inclusion graph n() on a finite dimensional vector space where the vertex set is the collection of nontrivial proper subspaces of a vector space and two vertices are adjacent if one is contained in other. The diameter, ...
vector space with respect to + and ·, with zero vector 0, then a set H ⊆ V is a subspace of V if 1 0 ∈ H 2 For every u, v ∈ H, u + v ∈ H. 3 For every u ∈ H and c ∈ R, c u ∈ H. EXAMPLE For any vector space V with zero vector 0, the set { 0} ...
1 关于subspace的题 Let Pol3(R) be the vector space of all polynomials of degree at most 3, with real coefficient,Let U be the subspace of all polynomials aX^3 + bX^2 + cX + d in Pol3(R) such that a+2b-c=a-b+d=0,and let V be the subspace of all polynomials of the form...

vector spaces V and V'. Since, however, every finite-dimensional vector space is reflexive, the identification convention of Problem 77 can and should be applied. According to that convention the space V' is the same as the space V, and both M and MI^(00) are subspaces of that space....
