The trianguline variety for reductive groups

Andrea Conti, Mohamed Moakher, Julian Quast

We study the trianguline variety for split connected reductive groups. We generalize a theorem of Breuil, Hellmann, and Schraen about its local structure, establishing smoothness o…

On Modified Diagonal Cycles and the Beauville Decomposition of the Ceresa Cycle

Lucas Lagarde, Mohamed Moakher, Morena Porzio +2

Let $C$ be a curve of genus $g \geq 2$ , and let $J$ be its Jacobian. The choice of a degree 1 divisor $e$ on $C$ gives an embedding of $C$ into $J$ ; we denote by $[C]_{}^{e}\in \ma…

Quantitative level lowering for weight two Hilbert modular forms

Mohamed Moakher

We generalize a result of Ribet and Takahashi on the parametrization of elliptic curves by Shimura curves to the Hilbert modular setting. In particular, we study the behaviour of t…

Symplectic determinant laws and invariant theory

Mohamed Moakher, Julian Quast

We introduce the notion of $symplectic determinant laws$ by analogy with Chenevier's definition of determinant laws. Symplectic determinant laws are a way to define pseudo…
