comment Is a good GRE score enough for a non-math graduate to be accepted in a decent pure mathematics graduate program?
What comes under the purview of weak math background in your opinion? Non-math undergrad major? Math Major with weak scores? Would a non-math undergrad major (engg/physics) with strong scores in math courses count as weak? Thank you.

comment Showing two matrices are similar
@Henning Sorry. I am following a physics book and these matrices are actually representations. Two representations were defined to be equivalent if their matrices are related by a similarity transformation. This was what I had in my mind.

comment Showing two matrices are similar
Yes, I am sure. The first three matrices are what physicists call spin 1 representation. The final three matrices are the adjoint representation of SU(2) (excluding a phase factor of -i). The question is to show that the two representations are equivalent (a result which is used later to construct roots). I phrased only the computational part in my question.

@J.M. But we're talking about polygons not polyhedrons.

comment Is there a binary spigot algorithm for log(23) or log(89)?
I'm wondering why I got notified without @. Anyhow, regarding the above comment, what has your reputation got to do with it?
