On real anti-bicanonical curves with one double point on the 4-th real
Hirzebruch surface [PDF]
Sachiko SaitoWe try to classify real anti-bi-canonical curves with one nondegenerate double point on the 4-th real Hirzebruch surface. They are closely related to real 2-elementary K3 surfaces of type ((3,1,1),-1). We also consider non-increasing simplest degenerations of real nonsingular anti-bi-canonical curves on the 4-th real Hirzebruch surface.View original: http://arxiv.org/abs/1209.3359
