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…
Deformations of pseudocharacters and Mazur's finiteness condition
Vytautas Paškūnas, Julian Quast
We show that deformation rings of -pseudocharacters of a profinite group are noetherian, when satisfies Mazur's finiteness condition. The proof proceed…
Symplectic determinant laws and invariant theory
Mohamed Moakher, Julian Quast
We introduce the notion of by analogy with Chenevier's definition of determinant laws. Symplectic determinant laws are a way to define pseudo…
Deformations of -valued pseudocharacters
Julian Quast
We define a deformation space of V. Lafforgue's -valued pseudocharacters of a profinite group for a possibly disconnected reductive group . We show, that this definition…
