Motivic, logarithmic, and topological Milnor fibrations
Jean-Baptiste Campesato, Goulwen Fichou, Adam Parusinski
We compare the topological Milnor fibration and the motivic Milnor fibre of a regular complex function with only normal crossing singularities by introducing their common extension…
Principal bundles and ad{è}les
Philippe Gille, Laurent Moret-Bailly
We investigate topological properties of torsors in algebraic geometry over adelic rings.
A global Weinstein splitting theorem for holomorphic Poisson manifolds
Stéphane Druel, Jorge Vitório Pereira, Brent Pym +1
We prove that if a compact Kähler Poisson manifold has a symplectic leaf with finite fundamental group, then after passing to a finite étale cover, it decomposes as the product of…
Computing isogenies between jacobians of hyperelliptic curves of arbitrary genus via differential equations
Elie Eid
Let be an odd prime number and be an integer coprime to . We survey an algorithm for computing explicit rational representations of -isogenies between Jacob…
Fixed point stacks under groups of multiplicative type
Matthieu Romagny
We prove that if a group scheme of multiplicative type acts on an algebraic stack with affine, finitely presented diagonal then the stack of fixed points is algebraic. For this, we…
Kashiwara's theorem for twisted arithmetic differential operators
Christine Huyghe, Tobias Schmidt
We establish a version of Kashiwara's theorem for twisted sheaves of Berthelot's arithmetic differential operators for a closed immersion between smooth p-adic formal schemes. As a…
