A lower bound theorem for centrally symmetric simplicial polytopes

Steven Klee, Eran Nevo, Isabella Novik +1

Stanley proved that for any centrally symmetric simplicial $d$-polytope $P$ with $d\ge 3$, $g_2(P)\ge \left(\genfrac{}{}{0ex}{}{d}{2}\right)-d$. We provide a characterization of centrally symmetric $d$-…
