PostDoc at the PDE group at EPFL. I tend to like working with evolution equations from general relativity and Lagrangian field theories.

Finding conditions to guarantee existence of solutions to IVP
There are two parts to your question: (a) is the local existence, which is essentially addressed by Peano. (b) is the semi-global existence (solution exists for all $t\geq 0$), this is where conditions on $b(t)$ and $x_0$ seems to be more relevant. Can you please clarify your question? |

Can there be ordinals larger than those contained in Ord, and if so, can they be used to extend the constructible universe $L$?
@ThomasBenjamin: I hope you don't mind my editing. For the sake of those TL;DR-inclined, I moved your simplified question from the bottom of the post to near the top, where it would be more visible. |

I've voted to close as off-topic as this question belongs better at matheducators.stackexchange.com |

“Almost” zeta function
@GHfromMO of course. Edited to incorporate your comment. (P.s. where I come from $\ll$ means something quite different and $\lesssim$ is usually used instead. I was honestly confused by your original comment.) |

“Almost” zeta function
Another typo: $$a_n < 1 \implies a_n^2 < a_n \implies n^{1 + a_n^2} < n^{1 + a_n} $$ so you probably want the two swapped in terms of convergence. |
