本文给出了光滑曲线上半稳定向量丛的独立整体截面数的上界的经典Clifford定理的一个改进。我们还猜想了这个定理的一个新版本,它考虑了曲线的Clifford指数。在双椭圆曲线的情况下,我们得到了一个非常精确的界。最后,我们研究了2阶丛的情形。
We give here a refinement of the classical Clifford's theorem for the upper bound of the number of independent global sections of a semistable vector bundle on a smooth curve. We also conjecture a new version of this theorem that takes into account the Clifford index of the curve. In the case of a bi-elliptic curve we obtain a very precise bound. Finally we study the case of rank 2 bundles.
