Аннотация: For any flag simplicial complex Theta obtained by stellar subdividing the boundary of the cross polytope in edges, we define a flag simplicial complex Delta(Theta) whose f-vector is the gamma-vector of Theta. This proves that the gamma-vector of any such simplicial complex is the face vector of a flag simplicial complex, partially solving a conjecture by Nevo and Petersen. As a corollary we obtain that such simplicial complexes satisfy the Frankl-Furedi-Kalai inequalities.
