We prove that ifis a pattern of, then we can express the Schubert polynomialas a monomial times(in reindexed variables) plus a polynomial with nonnegative coefficients. This implies that the set of permutations whose Schubert polynomials have all their coefficients equal to either 0 or 1 is closed under pattern containment. Using Magyar’s orthodontia, we characterize this class by a list of twelve avoided patterns. We also give other equivalent conditions onbeing zero-one. In this case, the Schubert polynomialis equal to the integer point transform of a generalized permutahedron.
