    Undergrad What is the proof of this theorem in Vector Spaces ?

    You can try with this proof (apagoge). Suppose m > n. Each vector of L is a linear combination of vectors v1, ... , vn, then: w1 = a1(v1) + ... + an(vn) At least one a_i coefficient is not zero (wlog, suppose a1 ≠ 0). Let's multiply both sides of equation by (a1)^(-1): a1(v1) =...
