Jul 27 comment Solving a Laplacian in polar coordinates @Thomas According to the author of the book, there is no typo. I copied it correctly. Jul 27 asked Solving a Laplacian in polar coordinates May 31 comment quasi-finite maps to quasi-projective varieties? @MattE Yes, I was working in the algebraic category. May 27 answered Open properties of quasi-compact schemes May 25 answered quasi-finite maps to quasi-projective varieties? May 24 answered How to find a finite set of generators for $I \subset k[x_1, …, x_n]$ May 23 answered Geometric genus of a (possibly non-complete) intersection in P^n May 5 comment Kähler differentials not the same as regular differentials on a singular curve @Alan I'm guessing it has something to do with $y^2=x^3$ implying $2ydy=3x^2 dx$. Multiplying by $x$ gives $2xydy=3x^3 dx=3y^2 dy$ and dividing by $y$ gives $2xdy=3ydx$. Apr 28 answered Varieties given by non-algebraic equations
