MINKOWSKI DECOMPOSITION AND GENERATORS OF THE MOVING CONE FOR TORIC VARIETIES:
We prove that for smooth projective toric varieties, the Okounkov body of a |$T$|-invariant pseudo-effective divisor with respect to a |$T$|-invariant flag decomposes as a finite Minkowski sum of indecomposable polytopes, and that the set of these polytopes corresponds to a finite Minkowski basis whose elements span the extremal rays …
