  • Q`-cohomology projective planes and Enriques surfaces in characteristic two 
    Schütt, Matthias (s.l. : Association de l'Épijournal de Geometrie Algebrique, 2019)
    We classify singular Enriques surfaces in characteristic two supporting a rank nine configuration of smooth rational curves. They come in one-dimensional families defined over the prime field, paralleling the situation in ...
  • Twelve Rational curves on Enriques surfaces 
    Rams, Sławomir; Schütt, Matthias (New York, NY [u.a.] : Springer, 2021)
    Given d∈ N, we prove that any polarized Enriques surface (over any field k of characteristic p≠ 2 or with a smooth K3 cover) of degree greater than 12 d2 contains at most 12 rational curves of degree at most d. For d> 2 , ...
