Algebro-geometric characterization of Cayley polytopes
伊藤敦Atsushi Ito) 博士後研究員(日本京都大學 下午 2:30–4:00 Hongjing Hall 107 室Abstract : Cayley polytopes are integral polytopes which are “small” in some sense.
In this talk, I give an algebro-geometric characterization of Cayley polytopes by
corresponding toric varieties.
As a corollary, we determine when the Seshadri constants of toric varieties are one.
