本文证明了亏格g>=2的Castelnuovo曲线上的半可态向量丛具有θ因子。作为推论,我们推导出:在g>=2的光滑一般曲线上,推广到一般曲线的任何Castelnuovo退化上的半可态向量丛,允许一个θ因子。

英文摘要:
In this paper we show that semistable vector bundles on a Castelnuovo curve of genus g >= 2 have theta divisors. As a corollary, we deduce that semistable vector bundles on a smooth, general curve of genus g >= 2 which extend to semistable vector bundles on any Castelnuovo degeneration of the general curve admit a theta divisor.
