Finiteness properties of torsion fields of abelian varieties
Wojciech Gajda, Sebastian Petersen
Let be an abelian variety defined over a field We study finite generation properties of the profinite group and of certain closed normal subgroups ther…
Remarks on a theorem of Pink in presence of bad reduction
Wojciech Gajda, Marc Hindry
In this note we prove new cases of the Mumford-Tate conjecture by extending a theorem of Richard Pink for abelian varieties without nontrivial endomorphisms and with bad semistable…
Local to global principles for homomorphisms of abelian schemes
Wojciech Gajda, Sebastian Petersen
Let and be abelian varieties defined over the function field of a smooth algebraic variety We establish criteria, in terms of restriction maps to subvarieties…
On the semisimplicity of reductions and adelic openness for -rational compatible systems over global function fields
Gebhard Böckle, Wojciech Gajda, Sebastian Petersen
Let be a normal geometrically connected variety over a finite field of characteristic~. Let be a number field. Using automorphic methods over global function fields,…
A variational open image theorem in positive characteristic
Gebhard Böckle, Wojciech Gajda, Sebastian Petersen
In this note we prove a variational open adelic image theorem for the Galois action on the cohomology of smooth proper -schemes where is a smooth variety over a finitely gen…
Big monodromy theorem for abelian varieties over finitely generated fields
Sara Arias-de-Reyna, Wojciech Gajda, Sebastian Petersen
An abelian variety over a field K is said to have big monodromy, if the image of the Galois representation on l-torsion points, for almost all primes l contains the full symplectic…
