Orta Doğu Teknik Üniversitesi ODTÜ-Bilkent Cebirsel Geometri SeminerleriLines in polarized K3-surfaces Alexander Degtyarev
I will explain the proof of my conjectures (reported earlier in this seminar) on the maximal number of straight lines in sextic surfaces in P4, (42 lines) and octic surfaces/triquadrics in P5, (36 lines). I will also try to make it clear that the complexity of the problem decreases when the polarization grows. The asymptotic bound for K3-surfaces in large projective spaces is 24 lines, all constituting fiber components of an elliptic pencil.
