 Apr10 accepted Computing the ring of integers of a number field Dec23 awarded Caucus Oct9 comment On Rieman integral Taking square roots is a well-defined continuous (hence integrable) function. Jun6 revised A variation of Kuratowski closure-complement problem using dual cones OP changed the question. May28 suggested rejected edit on A variation of Kuratowski closure-complement problem using dual cones May28 answered A variation of Kuratowski closure-complement problem using dual cones Dec23 awarded Yearling Feb23 comment On the ring of integers of a compositum of number fields Dear Bruno, can this solution be modified to find the ring of integers in case that none of $m$ and $n$ are 1 mod 4? Feb23 comment Computing the ring of integers of a number field Bruno, thanks; this seems a useful result to keep handy. Feb23 comment Computing the ring of integers of a number field Too bad if so.. :( Feb23 comment Computing the ring of integers of a number field Qiaochu, I have edited the question. Feb23 revised Computing the ring of integers of a number field added 4 characters in body Feb23 asked Computing the ring of integers of a number field Aug12 comment Find an ideal $I$ of $\mathbb{Z}[i]$ such that $\mathbb{Z}[i]/{I}$ is a field What is R in the question? Aug12 answered Find an ideal $I$ of $\mathbb{Z}[i]$ such that $\mathbb{Z}[i]/{I}$ is a field Jun13 comment Let $X = \Bbb{R}$ with the discrete metric. Is $X$ connected? @BrandonCarter There are stories of Emil Artin hurling a chalk or duster towards a student who'd ask What about the empty set?" Jun12 comment Is the sum and difference of two irrationals always irrational? $\sqrt 2 - 1$ is irrational being the sum of a rational and an irrational. Jun12 comment Let $X = \Bbb{R}$ with the discrete metric. Is $X$ connected? No discrete topology can ever be connected. You answer your own question. What do you mean by "formal way"?
