A new family of triangulations of $\mathbb{R}P_d$

Lorenzo Venturello and Hailun Zheng

Abstract

We construct a family of PL triangulations of the $d$-dimensional real projective space $\mathbb{R}P^d$ for every $d\geq 1$ on $\Theta((\frac{1+\sqrt{5}}{2})^{d+1})$ vertices. This improves a construction due to K\"{u}hnel on $2^{d+1}-1$ vertices.
