Cover picture from Marco Franciosi, Rita Pardini, and Sönke Rollenske, Math. Nachr. 290 (5–6), 794–814 (2017), DOI 10.1002/mana.201600090 . This is (a real picture of) a stable degeneration of a complex algebraic surface of general type withK X 2 = 1 and χ ( O X ) = 3 . The only two singular points are simple elliptic singularities of degree 1 and the minimal resolution is a rational surface.
