Query: Divisorial models of normal varieties   We prove that the canonical ring of a canonical variety in the sense of de
Fernex and Hacon is finitely generated. We prove that canonical varieties are
klt if and only if R(-K_X) is finitely generated. We introduce a notion of
nefness for non-Q-Gorenstein varieties and study some of its properties. We
then focus on these properties for non-Q-Gorenstein toric varieties.
