Real structures on complex surfaces: existence, finiteness, and quasi-simplicity
The subject of the talk is motivated by recent achievements in topological and deformation theories of real algebraic surfaces. It will concern some particular, previously almost ignored, questions like the possibility to deform a complex surface into a surface with a real structure, finiteness of real structures, or the relation between deformation and topological equivalences of real structures. I will survey the few results obtained in this direction.
