[Together with (iii), this shows that ‘V and Ware isomorphic if and only if dim(V) = dim(W)’.] Solution. Let n= dim(V) = dim(W). Let fv 1;:::;v ...

Furthermore, if dim(W) = dim(V), then W=V. Proof. Let Ibe a maximal independent set in W Such a set exists and is nite because of the fundamental inequality. Ispans W, and so is a basis for W. This is due to the dependence lemma showing that spanI= W.
Webplication W 1 ⊂ W 2 =⇒ dim(W 1) = dim(W 1 ∩W 2) becomes a trivial statement. On the other hand we can consider the basis for the subspace W 1 ∩ W 2 and we call it β ∩. The we can extend this basis to a basis if W 1 and call it β 1. Then the statement: dim(W 1) = dim(W 1 ∩ W 2) is equivalent to the statement β 1 = β WebIf V = {0}, then dimU = 0 and there is nothing to prove; so we may assume that V ≠ {0}. Let v 1 ∈ V be nonzero. If span{v 1} = U, then dimV = 1. If span{v 1} ≠ V, then there is a v 2 ∈ V …
