(You can work through the definition of a vector space to prove this is true.) As a $\mathbb{Q}$-vector space, $\mathbb{C}^2$ is infinite-dimensional, and you can't write down any nice basis. (The existence of the $\mathbb{Q}$-basis depends on the axiom of choice.) You are seeking coordinate vectors x, y in R4 such that U(1)x = U(2)y. This I understand. Since I'm looking for the intersection of the two vector spaces, the equality holds because I can express a vector in the basis of U(1) as a vector in the basis of U(2) exactly because they intersect. So you want to solve U(1)x - U(2)y = 0 for (x, y) in R8.I am given these two vectors (1,2), (2,1) and i know that for a set of vectors to form a basis, they must be linearly independent and they must span all of R^n.
