令 $$ C \subset {\mathbb{P}^r} $$ 为具有指定亏格的一般平滑曲线的指定次数的一般嵌入。这里我们证明 $$ {h^0}\left( {{\mathbb{P}^r},{\mathcal{I}_C}(2)} \right) = 0 $$ 或 $$ {h^1}\left( {{\mathbb{P}^r},{\mathcal{I}_C}(2)} \right) = 0 $$ (一个称为最大秩猜想的问题,范围为二次曲面)。
Let $$ C \subset {\mathbb{P}^r} $$ be a general embedding of prescribed degree of a general smooth curve with prescribed genus. Here we prove that either $$ {h^0}\left( {{\mathbb{P}^r},{\mathcal{I}_C}(2)} \right) = 0 $$ or $$ {h^1}\left( {{\mathbb{P}^r},{\mathcal{I}_C}(2)} \right) = 0 $$ (a problem called the maximal rank conjecture in the range of quadrics).
