Unramifiedness of Galois representations attached to weight one Hilbert modular eigenforms mod p [PDF]

open access: yes, 2018
peer reviewedThe main result of this article states that the Galois representation attached to a Hilbert modular eigenform defined over F_p^bar of parallel weight 1 and level prime to p is unramified above p.

SERRE WEIGHTS AND BREUIL’S LATTICE CONJECTURE IN DIMENSION THREE

open access: yesForum of Mathematics, Pi, 2020
We prove in generic situations that the lattice in a tame type induced by the completed cohomology of a $U(3)$-arithmetic manifold is purely local, that is, only depends on the Galois representation at places above $p$. This is a generalization to $\text{

TORSION GALOIS REPRESENTATIONS OVER CM FIELDS AND HECKE ALGEBRAS IN THE DERIVED CATEGORY

open access: yesForum of Mathematics, Sigma, 2016
We construct algebras of endomorphisms in the derived category of the cohomology of arithmetic manifolds, which are generated by Hecke operators. We construct Galois representations with coefficients in these Hecke algebras and apply this technique to ...

Finiteness properties of the category of mod p representations of ${\textrm {GL}}_2 (\mathbb {Q}_{p})$

open access: yesForum of Mathematics, Sigma, 2021
We establish the Bernstein-centre type of results for the category of mod p representations of $\operatorname {\mathrm {GL}}_2 (\mathbb {Q}_p)$ . We treat all the remaining open cases, which occur when p is $2$ or $3$ .

On a variation of the Erdős–Selfridge superelliptic curve

open access: yesBulletin of the London Mathematical Society, Volume 51, Issue 4, Page 633-638, August 2019., 2019
Abstract In a recent paper by Das, Laishram and Saradha, it was shown that if there exists a rational solution of yl=(x+1)…(x+i−1)(x+i+1)…(x+k) for i not too close to k/2 and y≠0, then logl<3k. In this paper, we extend the number of terms that can be missing in the equation and remove the condition on i.

On elliptic curves with an isogeny of degree 7 [PDF]

open access: yes, 2010
ON ELLIPTIC CURVES WITH AN ISOGENY OF DEGREE 7 arXiv:1007.4617v3 [math.NT] 16 Oct 2012 R. GREENBERG, K. RUBIN, A. SILVERBERG, AND M. STOLL Abstract. We show that if E is an elliptic curve over Q with a Q-rational isogeny of degree 7, then the image of ...

DERIVED HECKE ALGEBRA AND COHOMOLOGY OF ARITHMETIC GROUPS

open access: yesForum of Mathematics, Pi, 2019
We describe a graded extension of the usual Hecke algebra: it acts in a graded fashion on the cohomology of an arithmetic group $\unicode[STIX]{x1D6E4}$.

Modularity of the Consani-Scholten quintic. With an appendix by José Burgos Gil and Ariel Pacetti

open access: yesDocumenta Mathematica, 2012
We prove that the Consani-Scholten quintic, a CalabiYau threefold over Q, is Hilbert modular. For this, we refine several techniques known from the context of modular forms.

ON THE INTEGRAL HODGE AND TATE CONJECTURES OVER A NUMBER FIELD

open access: yesForum of Mathematics, Sigma, 2013
Hassett and Tschinkel gave counterexamples to the integral Hodge conjecture among 3-folds over a number field. We work out their method in detail, showing that essentially all known counterexamples to the integral Hodge conjecture over the complex ...
