Edge connectivity of simplicial polytopes

Vincent Pilaud, Guillermo Pineda-Villavicencio, Julien Ugon

We show that the graph of a simplicial polytope of dimension $d \geq 3$ has no nontrivial minimum edge cut with fewer than $d (d + 1) /2$ edges, hence the graph is $min {δ, d (d + 1) /2}$ …

Cycle space of graphs of polytopes

Guillermo Pineda-Villavicencio

It is folklore that the cycle space of graphs of polytopes is generated by the cycles bounding the 2-faces. We provide a proof of this result that bypass homological arguments, whi…
