 2d awarded Guru Apr 23 revised Jacobson ring = a ring whose nilradical and Jacobson radical coincide? deleted 452 characters in body Apr 17 comment Cardinality of connected Hausdorff topologies @Gerald: Indeed, if I understand the "suspension" procedure correctly, doing it with a one-point space and a two-point space will yield homeomorphic spaces. Apr 15 awarded Enlightened Apr 15 awarded Nice Answer Apr 12 awarded Good Answer Apr 9 comment Elementary / Interesting proofs of the Nullstellensatz This proof looks rather similar to one given in a 1976 Monthly note of McCabe: see alpha.math.uga.edu/~pete/McCabe76.pdf. Also see Section 11.1.2 of alpha.math.uga.edu/~pete/integral2015.pdf for a writeup of McCabe's proof of a similar length to that of Azarang's. Mar 28 awarded Notable Question Mar 26 comment Famous mathematical quotes Last year our distinguished Cantrell Lecture series was given by Dick Gross. I had been booked as a speaker in the graduate student seminar, which took place immediately before Gross's first lecture. I decided to give an introduction to elliptic curves, including BSD and Gross-Zagier. I made sure to include this quote of Tate. So did Gross in his first lecture. Mar 26 comment Famous mathematical quotes @Amr: Well, I'm certainly not. On the one hand, a quotation is not an endorsement. On the other hand, although you perceive -- I believe correctly -- constructivist principles in the provenance of the quote, it is a good enough quote that it can mean other things as well. As a piece of general mathematical advice, I find it quite sound. Mar 26 comment CM $j$-invariants in $p$-adic fields Very interesting.
