What integer value can be the conductor of a $g$-dimensional abelian variety over $\mathbb Q$?
Thank you! I want to know possible value of $N$, is your bound for valuation of $N$ the optimal bound?

Dimension of fixed vectors of a semi-linear operator
Thank you! I know this case, which is similar to a classical argument in $p$-adic Galois representations that $\dim D(V) \leq \dim V$ for any admissible period ring.

rank of Jacobian of Fermat curve and Chabauty-Coleman method
Thank you, I didn't notice that paper, it seems for regular primes the bound is true.

Endomorphism ring of $J_0(p)$ and Hecke operators
Thank you ! I shall look at Mazur's paper (as it's two years after Ribet's paper on semistable abelian varieties ) for some hints.

generalization of the discreteness of Hecke groups to general reductive groups
@Misha Thank you for that answer.. How about other groups? For example $SL_3(\mathbb R)$?

If a polynomial ring is a finite flat module over some subring, is that subring itself a polynomial ring?
@DavidESpeyer Thank you for some hints! I will think about it..
