WebI have come across the following claim: The distance (induced by the Frobenius norm) between any two (non equal) orthogonal matrices is $\sqrt{n}$. I can't find a proof for this claim, but no refutation either (of course, if the difference between two orthogonal matrices is itself an orthogonal matrix the claim is clear, but I don't know if that's true either). WebThe $2$-norm is the usual notion of straight-line distance, or distance ‘as the crow flies’: it’s the length of a straight line segment joining the two points. The $1$-norm gives the distance if you can move only parallel to the axes, as if you were going from one intersection to another in a city whose streets run either north-south or east-west.

WebThe norm gives the length of a a vector as a real number (see def. e.g. here). I further understand that all normed spaces are metric spaces (for a norm induces a metric) but not the other way around (please correct me if I am wrong). Here I am only talking about vector spaces. As an example lets talk about Euclidean distance and Euclidean norm.
