Abstract
<jats:p xml:lang="en">We show that given a poset $P$ and and a subposet $Q$, the integer points obtained by restricting linear extensions of $P$ to $Q$ can be explained via integer lattice points of a generalized permutohedron.</jats:p> <jats:p xml:lang="fr">Nous montrons que, étant donné un poset $P$ et un subposet $Q$, les points entiers obtenus en restreignant les extensions linéaires de $P$ à $Q$peuvent être expliqués par les points entiers d’un permutohedron généralisé.</jats:p>
