The Neron model over the Igusa curves
Christian Liedtke, Stefan Schroeer
We analyze the geometry of rational p-division points in degenerating families of elliptic curves in characteristic p. We classify the possible Kodaira symbols and determine for th…
Unirational Surfaces on the Noether Line
Christian Liedtke, Matthias Schuett
We show that among simply connected surfaces of general type unirationality is a common feature, even when fixing the positive characteristic or numerical invariants. To do so, we…
A note on non-reduced Picard schemes
Christian Liedtke
The Picard scheme of a smooth curve and a smooth complex variety is reduced. In this note we discuss which classes of surfaces in terms of the Enriques-Kodaira classification can h…
Non-classical Godeaux Surfaces
Christian Liedtke
A non-classical Godeaux surface is a minimal surface of general type with but with . We prove that such surfaces fulfill and they can exist only o…
