Selmer complex and total complex

You should view the morphisms of complexes of the notation with Tot as complexes of complexes concentrated in only two degrees with differential given by the morphism, which is a particularly simple c …

Could I get an interpretation for application of Euler characteristics in number theory?

If $\rho$ is a Galois representation of geometric origin and if you consider a cohomology complex $C$ computing Galois cohomology satisfying (supplementary cleverly) defined arithmetic conditions, the …

Proven results for the refined Birch Swinnerton-Dyer conjecture over rationals when rank at ...

I think that the answer to your questions depends in subtle ways on whether $r=0$ or $r=1$. In full generality, I believe you are right that none of the properties you state are known for all elliptic …

$n$-torsion fields of an elliptic curve defined over $\mathbb{Q}$

Going in the other direction, the Néron-Ogg-Shafarevich criterion and Weil pairing imply that the Tate module $T_{\ell}E$ is a Galois representation which is ramified at $p$. So if $n$ is large enough …

Discrepancy in the calculation of $2$-Selmer group by Magma and LMFDB

I don't see any contradiction: the Selmer group also has a contribution of rational points. Indeed, the group of 2-torsion rational points on this elliptic curve is isomorphic to $\mathbb Z/2\mathbb Z …

Is Galois representation induced by semistable elliptic curve semistable?

A Galois representation $\rho_\ell:\operatorname{Gal}(\bar{\mathbb Q}_{\ell}/\mathbb Q_{\ell})\longrightarrow\operatorname{GL}_2(\mathbb Q_{\ell})$ can be semistable (technically $B_{st}$-admissible i …

Motivation of the construction of $p$-adic period rings

How did we end up with the such complicated constructions of $B$? To add to Laurent's answer remark that "these rings did not, however, come out of nowhere", I believe that in the early 80s, Fontain …

References for the early history of Fontaine's tilting construction

Jean-Marc Fontaine Groupes p-divisibles sur les corps locaux. Astérisque 47-48, Soc. Math. France, Paris (1977), i+262 pp (especially chapter V) This is probably the canonical answer to your question …

Endomorphism ring of $J_0(p)$ and Hecke operators

EDIT: This is an answer to a different question, namely whether removing operators other than $U_p$ can result in a strict sub-algebra. In particular, the example given shows that $\mathbb T^{(2)}$ is …

Some questions on the $p$-adic properties of special $L$-values

1) What generalizations of the Kummer congruences are known? This is somewhat imprecise as a question and in particular, I would dispute a little your assertion that This is probably the same …

In addition to François's answer, I'll address the second question. Are there any differences between the case over $\mathbb Q$ and a number fields $L$? The main difference - which can be dealt …

More explicitly, I would like to know if from these motives $M_{f}$ I can create an $\ell$-adic representation with values in some object of cohomological nature arising from $M_{f}$ (like motivic …

Are overlaps among {algebraic geometry, arithmetic geometry, algebraic number theory} growing?
