I am a second year PhD student interested in the fundamental lemma and the Langlands programme. I also like homological algebra.

What arithmetic information is contained in the algebraic K-theory of the integers That's ok, I was in a hurry typing this and admittedly did not read the question as thoroughly as I should have. |

Reference for Rationality in Algebraic Groups in the Language of Schemes? @ayanta: thank you for the references, I'll take a look. @Kidwell: I have taken a look at B. Conrad's notes from his course now and these are essentially the kind of thing I want. If you post your comment as an answer, I shall accept it. @Putman: Thank you also for the link; the notes look promising as well, and I'll keep an eye out for their progress. |

Reference for Rationality in Algebraic Groups in the Language of Schemes? @ayanta: yes sorry, I was being sloppy. I am aware that not all groups are split or quasisplit. The result on the existence of split and quasisplit forms is one thing for example that I‘d like to see. @Kidwell: thanks, I will take a look at these notes! |

Homotopy-theoretic measure of operations on sheaves failing to be sheaves @Jacob: Yes for qc, this is essentially the third paragraph. |

Nice Algebraic Statements Independent from ZF + V=L (constructibility) (I meant to say $\mathrm{Ext}^1(A,\mathbb{Z}) = 0$) |

Nice Algebraic Statements Independent from ZF + V=L (constructibility) Thank you for the detailed answer. Since forcing extensions cannot satisfy $ZFC + V=L$, what about considering some theory that does not satisfy $V=L$. For instance, in some models, nonfree abelian groups $A$ with $\mathrm{Ext}^1(A,\mathbb{Z})$ do exist, so would it be easier to find further algebraic statements in such models that are independent? |

Nice Algebraic Statements Independent from ZF + V=L (constructibility) Your question, also interesting, looks for open problems that were proven in some definition of "countable case" and not necessarily independent or implied by stronger set theoretic axioms, so I am hoping that the different criteria and wording might prompt some answers. |

The non-traveling mathematician problem Even if you go to four conferences a year lasting a week each, which to me seems like a lot, that's four weeks a year....is it too much for you to be away from your family for that long??? |
