WebSpan: implicit deﬁnition Let S be a subset of a vector space V. Deﬁnition. The span of the set S, denoted Span(S), is the smallest subspace of V that contains S. That is, • Span(S) is a subspace of V; • for any subspace W ⊂ V one has S ⊂ W =⇒ Span(S) ⊂ W. Remark. The span of any set S ⊂ V is well deﬁned Web17. sep 2024 · In other words, a subspace contains the span of any vectors in it. If you choose enough vectors, then eventually their span will fill up V, so we already see that a subspace is a span. See this Theorem 2.6.1 below for a precise statement.
