I want to share a book, but can’t bare to part with any of my good ones. I’m going to go hunt for a book in humanities 3, one was released there.
Don’t think it’ll be there but you never know.
Back to the P-F theorem, in the 2×2 matrix case, with positive entries. I think I’ve found the eigenvalues and they are both positive… hmm.. that can’t be right.. what if one is zero?
better check that..
