Topological classification of real Enriques surfaces
A real Enriques surface is a complex Enriques surface equipped with an antiholomorphic involution (complex conjugation). The fixed point set of this involution is called the real part of the surface. The authors complete the classification of topological types of real Enriques surfaces started by V. Nikulin. It contains 87 topological types which are obtained, from a list of 22 extremal cases, by applying Morse simplifications (namely, removing components or contracting a handle).
