... definition of S(i, d) (1 ≤ r ≤ i). Proof. In the definition of S(i, d) let the set of vertices of σ r be F ⊎{v}. Then the number of j-faces in S(i, d) containing v is f j−1 (S(i, d−1)), of those containing ... details. • Conjecture 1.4 for flag homology spheres of dimension ≤ 4 holds. Gal showed nonnegativity of the γ-polynomial in this case [8], based on the Davis-Okun proof [...
