$\mathbb{Q}$ -扭层的M-正则性及其在线性系簇上的应用

M-regularity of $\mathbb{Q}$-twisted sheaves and its application to linear systems on abelian varieties

Atsushi Ito

摘要:

G. Pareschi和M. Popa在M-正则性理论中给出了阿贝尔簇上凝聚层的整体瓣的乘法映射的整体生成和满射性的判别准则。本文利用$\mathbb{Q}$ -扭层的M-正则性,推广了他们的一些判据。作为应用,我们证明了一个合适的$\mathbb{Q}$ -扭曲层的M-正则性意味着性质$(N_p)$和喷满的充足线丛阿贝尔簇。

英文摘要:

G. Pareschi and M. Popa give criterions for global generations and surjectivity of multiplication maps of global sections of coherent sheaves on abelian varieties in the theory of M-regularity. In this paper, we generalize some of their criterions via the M-regularity of $\mathbb{Q}$-twisted sheaves. As an application, we show that the M-regularity of a suitable $\mathbb{Q}$-twisted sheaf implies property $(N_p)$ and jet-ampleness for ample line bundles on abelian varieties.
