Stable cohomology of moduli spaces of hyperelliptic curves on Hirzebruch surfaces
Jonas Bergström, Angelina Zheng
We compute the stable cohomology of moduli spaces of hyperelliptic curves of a fixed genus embedded on a fixed Hirzebruch surface. We also describe these moduli spaces of embedded…
Cohomology of moduli spaces via a result of Chenevier and Lannes
Jonas Bergström, Carel Faber
We use a classification result of Chenevier and Lannes for algebraic automorphic representations together with a conjectural correspondence with -adic absolute Galois represe…
Polynomial point counts and odd cohomology vanishing on moduli spaces of stable curves
Jonas Bergström, Carel Faber, Sam Payne
We compute the number of F_q-points on M_{4,n}, for n less than or equal to 3, and show that it is a polynomial in q, using a sieve based on Hasse-Weil zeta functions. As an applic…
On the Brauer group of bielliptic surfaces
Jonas Bergström, Eugenia Ferrari, Sofia Tirabassi +1
We provide explicit generators for the torsion of the second cohomology of bielliptic surfaces, and we use this to study pullback map between Brauer group of a bielliptic surface a…
