内容記述 | This paper is devoted to the study of the next extremal case for a Castelnuovo-type bound regC ≤ ⎾(degC-1)/codimC⏋+max{k(C),1} for the Castelnuovo–Mumford regularity for a nondegenerate projective curve C, where k(C) is an invariant which measures the deficiency of the Hartshorne–Rao module of C. We show that a projective curve with next to the maximal regularity lies on either a Hirzebruch surface or a normal del Pezzo surface. |
