The upper limit topology on ℝ is defined by the basis ℬ = {(a,b] s.t. a < b for all a,b ∈ ℝ}. True or False?
5. Let V be a vector space (note that this is an arbitrary vector space - not necessarily F"). Suppose dim(V) = n. Prove that a set of vectors (v₁,..., Vn} in V is linearly independent if and only if it spans V. • Hint 1: Remember (from sec. 1.6) that there is always an isomorphism A: V → F and isomorphisms "preserve" bases (and so preserves linear independence). Hint 2: Think in terms of pivots.
