 Jan 5 awarded Notable Question Nov 3 awarded Yearling Oct 27 awarded Popular Question Oct 4 asked Find open set of variety with fibers of pure dimension Sep 26 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. Sep 26 comment Krull dimension $\leq$ transcendental degree Could you explain this? What are the prime ideals of $B$?

Jul 4 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!

Thank you very much, now the result follows trivially Jun 27 accepted principal curvature of the flat torus Jun 27 asked principal curvature of the flat torus
