Toric 3-folds defined by quadratic binomials

Shoetsu Ogata

Published 2020-04-09Version 1

Let $(X, A)$ be a polarized nonsingular toric 3-fold with not effective $A+K_X$. Then for any ample line bundle $L$ on $X$ the image of the embedding by the complete linear system of $L$ is an intersections of quadrics.
