Canonical models of surfaces of general type in positive characteristic
On supersingular curves and Abelian varieties.
Shellability of a poset of polygonal subdivisions.
On minimal models in integral homotopy theory.
On total reality of meromorphic functions
We show that, if a meromorphic function of degree at most four on a real algebraic curve of an arbitrary genus has only real critical points, then it is conjugate to a real meromorphic function by a suitable projective automorphism of the image.
