... Show that it is a vector space. ( To save time, you need only prove axioms (d) & (j), and closure under all linear combinations of 2 vectors.) Show that any subspace of R3 must pass thru the origin, and so any subspace of R3 must involve zero in its description. Does the converse hold? Does any subs ...

... by 1, which makes a mess of the signs in the axioms: • [a, b] = (−1)(|a|+1)(|b|+1) [b, a], • [a, [b, c]] = [[a, b], c] + (−1)(|a|+1)(|b|+1) [b, [a, c]], • [a, b · c] = [a, b] · c + (−1)(|a|+1)|b| b[a, c]. Define Gersti (n) to be the space of Z-linear combinations of n-ary operations of degree i on Ge ...

... Page 138, Ex. 17. Let x1 , . . . , xk be linearly independent vectors in Rn , and let A be a nonsingular n × n matrix. Define yi = Axi for i = 1, . . . , k. Prove that y1 , . . . , yk are linearly independent. Note first that matrix multiplication by any matrix B preserves linear combinations; that ...
