= Lattice polytope of a toric divisor
{title2=$P_D$}

For an invariant divisor $D=\sum_\rho a_\rho D_\rho$, its lattice polytope is
$$
P_D=\{m\in M_{\mathbb R}:\langle m,v_\rho\rangle\geq-a_\rho\text{ for every }\rho\}.
$$
Its lattice points index torus-character sections of the associated <line bundle>.
