Makoto Enokizono, Normal stable degenerations of Noether-Horikawa surfaces
B236-1 IBS, Korea, Republic ofAlgebraic Geometry SeminarSpeaker Makoto Enokizono University of Tokyo Noether-Horikawa surfaces are surfaces of general type satisfying the equation K2=2pg−4, which represents the equality of the Noether inequality K2≥2pg−4 for surfaces of …
