... that if V has a finite basis, then every linearly independent set having the same number of vectors is also a basis. This result is the content of the next section. However, to prove it we need the Extension theorem. Corollary 1.4.1. If S = {v1 , . . . , vk } is linearly dependent then the represent ...

... As conditions (1),(2),(3) are all valid, H is a subspace of V . The above proof allows obvious generalization to: Thm 1 (P.210): For any v1 , . . . , vp ∈ V , the collection of vectors H = Span {v1 , . . . , vp } is a subspace of V . Note: We will call H to be the subspace spanned (or generated) by ...

The Zero-Sum Tensor
... On the topic of rare matrices, some properties of a matrix, here defined as a zero-sum matrix, are analyzed and three rules are derived governing multiplication involving such matrices. The suggested category (the zero-sum matrix) does not seem to presently exist, and is as expected neither included ...

... Sn−1 to both sides. Since Sn = 0, all the terms except the first one vanish, and we have c1 Sn−1 v = 0, and hence c1 = 0 because Sn−1 v 6= 0. Now we can similarly apply Sn−2 to show that c2 = 0, and so on (this may again be formalized by induction if desired), and we conclude that all the c j are 0 ...
