comment Krull dimension $\leq$ transcendental degree
I care about the prime ideals because I want to know the krull dimension of $B$. The reason for this is that I was expecting it to be strictly less than $2$, which is the transcendence degree of $frac(B)$. If that is the case I would have a nice example of a subring of a finitely generated $k-algebra$ for which krull dimension and transcendence degree do not agree. Part 1 of my question has apparently already been answered at mo.

Could you explain this? What are the prime ideals of $B$?

comment equivalent definitions of tensorfields
@jack lee Oh I have an older edition of the same, in which I didn't succeed to find it! A great book however! Very clear and inspiring!

comment principal curvature of the flat torus
Ofcourse, I get confused in finding the normal space, unused to complex scalar products or something. Thank you very much, now the result follows trivially
