I'm a PhD student with research interests in Algebraic Geometry, Algebraic Complexity Theory and Computer Algebra, i.e. doing delicate algebra to come up with powerful algorithms.

Two ramified covers $\Rightarrow$ reducible ramification divisor? Certainly not in this generality, e.g. it won't happen if both morphisms are étale. |

Expression of basis vectors of permutation modules in different bases. @Aaron: Do you mean Fulton's book? I didn't find anything on permutation modules in there. I am unaware of a book by Humphreys on Young Tableaux. |

GCD in a subring is GCD in a bigger ring @JiangweiXue: A GCD $d$ of $r_1,\ldots,r_n$ is a maximal element in the set of elements that divide all the $r_i$, with respect to the divisibility relation. In other words: $d$ divides all the $r_i$ and if any $d'$ divides all the $r_i$, then it follows that $d'\mid d$. |

A basis of the symmetric power consisting of powers @MartinBrandenburg: Good point(s), I edited the question accordingly. |
