I enjoy thinking about questions in commutative algebra which have connections to neighboring fields.

About regular local rings and Socles Youngsu, if depth M is $>0$ then the socle is $0$. |

About regular local rings and Socles Mohan, I think the question is about an injective resolution. Anyway, voted to close as this is not a real question. |

Higher dimensional Bezout via Hilbert polynomials: a reference. Dear Sándor, what I did not understand in Claim 1 was that while $Z(f_1,...,f_r)$ is of dimension $n-r$, it may have component of smaller dimensions. Perhaps I was missing something? |

Higher dimensional Bezout via Hilbert polynomials: a reference. Dear Sándor, Claim 1: why does any component have same dimension? And Claim 2: for $x$ to be a NZD you need it to be outside all associated primes, not just minimal. |

Algebraic vector bundles on affine punctured plane Or, one can quote algebraic Hartog's Lemma plus the fact mentioned above. |

Algebraic vector bundles on affine punctured plane Yes, use the Corollary after Theorem 4.1 in Horrocks' paper "Vector bundle on punctured..." plus the fact that any vector bundle on the whole affine plane is trivial. |

Factoriality vs $\mathbf{Q}$-factoriality for threefolds hypersurfaces with isolated singularities Dear Francesco, it looks fine to me. By the way, I forgot a more recent reference by Hartshorne-Polini, front.math.ucdavis.edu/1301.3222. |
