令 C 为 P n 中的算术布克斯鲍姆曲线,令 I C 为其理想曲线。我们通过集中于超平面截面来研究 C 和 I C,特别是对于 n= 3。例如,我们考虑将 I C∩ H(其中 H 是超平面)的元素提升到 I C 的问题,并由此得出有关 C 的联络类的一些结论。我们还尝试为 I C 的最小生成元的度给出良好的界限,并且在 C 是积分的情况下加强这些界限。我们还考虑相对于我们的一般界限而言的极值曲线。
Let C be an arithmetically Buchsbaum curve in P n and let I C be its ideal. We study C and I C by concentrating on hyperplane sections, especially for n= 3. For example, we consider the problem of lifting elements of I C∩ H (where H is a hyperplane) to I C, and from this we draw some conclusions about the liaison class of C. We also attempt to give good bounds for the degree of a minimal generator of I C, and we strengthen these bounds in case C is integral. We also consider curves which are extremal with respect to our general bounds.
