Background for the Elkies-Klagsbrun curve of rank 29
Very cool! (I hereby conjecture that there exist elliptic curves over ℚ of rank ≥ 30.)

Can a 2-sphere be squashed flat?
Don't forget to mention what your polygons are inscribed in.

Question on harmonic map between Riemannian manifolds
Fixed misspelling
comment
Reference request: acceleration/curvature of curve in metric space
For the overwhelming majority of continuous curves, this definition has no meaning (in an arcwise connected component of a metric space), because the limit does not exist.

System of quadratic inequations
I never bother to read past a point that I find to be inadequately explained.

System of quadratic inequations
In your three equations for s_i, can we assume that j = j(i) and k = k(i) ? That is, can we assume that the j and k in those equations are each functions of i ? If not, then I do not understand the question.

Gauss, Cantor, and infinite confusion
In Gauss's quote he does not appear to be discussing cardinalities of sets.

Positive mass theorem and Seiberg-Witten equations
Why not ask Zhang directly. His contact information is here: gxcmr.gxu.edu.cn/info/1096/1061.htm.

Is there a "simplest" way to embed a graph in 3-space?
Achieving the minimum crossing number, over all embeddings and all orthogonal projections to a plane, might be a start.
