I only looked at the first response to that question. Feb 11 awarded Commentator Feb 11 comment Subsequences of regular sequence @Matt: I don't think so. $x,z(1-x)$ and $x,y(1-x),z(1-x)$ are both regular there. Feb 11 asked Subsequences of regular sequence Feb 6 comment Why is the prime spectrum of a domain irreducible in the Zariski topology $0$ is the only minimal prime of $R$. Suppose, $R=V(I)\cup V(J)$. If $I,J$ are nonzero, then the zero ideal is in neither closed set. So, one of them must be zero, in which case, the corresponding closed set is the entire spectrum.

I guess if you choose a $V$ as above, then consider the neighbourhood of $1$ given by $V\cap (G-{{xy^{-1}}})$, then the intersection in my comment above is nonempty. Feb 2 comment Hausdorffness of a topological abelian group Why points are closed implies $G/H$ is $T_2$? Feb 2 comment Hausdorffness of a topological abelian group Thanks for the elaborate answer. I am still unable to see why $xV\cap yV=\emptyset$. Feb 1 asked Hausdorffness of a topological abelian group Feb 1 comment Completion of a polynomial ring w.r.t the homogeneous maximal ideal is the power series ring Thanks. Seems like a strange notation.

Jan 25 comment Intersection of powers of an ideal in a Noetherian ring @Akhil: Thanks a lot. That helps. Do you know if it's true in the regular case if $R$ is not local.
