Let G be a semisimple, simply connected linear algebraic group over an
algebraically closed field k of characteristic p > 0. In a recent paper [4],
Doty introduces the notion of r-minuscule weight and exhibits a tensor product
factorization of a corresponding tilting module under the assumption p >= 2h-2,
where h is the coxeter number. We remove the characteristic restriction and
generalize to a wider class of weights that we call (p,r)-minuscule.
