Thef-vector of a convexd-polytopePis the vectorf(P) = (f0(P),f1(P),…,fd− 1(P)), wherefj(P) is the number ofj-dimensional faces ofP. McMullen in 1971 proposed a characterization of the set of allf-vectors of simplicial convexd-polytopes. In 1979 the authors announced the sufficiency of the characterization and Stanley proved its necessity. We give here a proof of the sufficiency of McMullen's conditions.
