Schemes over a noetherian local ring and its completion Great example! If I understand correctly, the fact that $R$ has dimension $>1$ means that you can arrange a descent obstruction without touching the generic fiber of $\mathbb{P}^1_R$. |

Schemes over a noetherian local ring and its completion Nice! This example evaporates if I add an extra hypothesis on the generic fiber of $X$, so I will update my question. |

Catalan-type equations for prime powers Suppose that $p,p+k,p+2k$ is a $3$-term arithmetic progression of primes with $p$ large. Does one have any control over $k$? For example, is it possible to take $k \ll p^{1-\epsilon}$? |
