I have the same query after reading the paper.
Can the authors please comment?
I also don't understand the first question. : (
For the second one, I think the key is to prove that convex-looking regions in projected surface is relatively convex in original surface. A small absolute ratio means that the max eigenvalue is big enough compared to min eigenvalue which may be a negative value, that is the postive eigenvalue is dominant, so a convex-looking region in projected surface which has a small absolute ratio is a relatively convex region in original surface.
