Description
I will present an explicit geometric construction
of some special surfaces of general type described
by Schoen in 2007, that occupy an important place in the geography
of surfaces of general type. I will show how the construction
involves the Segre cubic, the Igusa quartic
and K3 quartic surfaces with fifteen nodes.
This is a joint work with Carlos Rito and Xavier Roulleau.
