The Seshadri Constants of Tangent Sheaves on Toric Varieties

Chih-Wei Chang

In this paper, we investigate the Seshadri constant $ε (X, T_{X}; p)$ of the tangent sheaf $T_{X}$ on a complete $Q$ -factorial toric variety $X$ . We show that $\varepsil…

Asymptotic constructions and invariants of graded linear series

Chih-Wei Chang, Shin-Yao Jow

Let $X$ be a complete variety of dimension $n$ over an algebraically closed field $K$ . Let $V_{∙}$ be a graded linear series associated to a line bundle $L$ on $X$ , th…
