Almost simplicial polytopes I. The lower and upper bound theorems

Eran Nevo, Guillermo Pineda-Villavicencio, Julien Ugon +1

We study $n$ -vertex $d$ -dimensional polytopes with at most one nonsimplex facet with, say, $d + s$ vertices, called {\it almost simplicial polytopes}. We provide tight lower and uppe…

Lower bound theorems for general polytopes

Guillermo Pineda-Villavicencio, Julien Ugon, David Yost

For a $d$ -dimensional polytope with $v$ vertices, $d + 1 \leq v \leq 2 d$ , we calculate precisely the minimum possible number of $m$ -dimensional faces, when $m = 1$ or $m \geq 0.62 d$ . This conf…
