Hasse invariant and group cohomology
Bas Edixhoven, Chandrashekhar Khare
Let p be a prime number. The Hasse invariant is a modular form modulo p that is often used to produce congruences between modular forms of different weights. We show how to produce…
Subvarieties of Shimura varieties
Bas Edixhoven, Andrei Yafaev
A conjecture by Yves Andre and Frans Oort says that closed subvarieties of Shimura varieties that contain a Zariski dense subset of special points are subvarieties of Hodge type. W…
On the Andre-Oort conjecture for Hilbert modular surfaces
Bas Edixhoven
We prove, assuming the generalized Riemann hypothesis, the Andre-Oort conjecture for Hilbert modular surfaces. More precisely, let K be a real quadratic field and let S be the coar…
On Néron models, divisors and modular curves
Bas Edixhoven
Let be a prime number such that the modular curve has genus at least two. We show that the only points of the reduction mod of with image in the reduction…
