Facet colouring of nestohedra
Апстракт
A proper colouring of a polytope is a surjective function from the set of facetsto a set ofmcolours such that every two facets associated with the same colour areseparated, i.e. have no vertex in common. The chromatic number of a polytope is theminimalmsuch that there exists a proper colouring of its facets inmcolours. Thistalk presents the chromatic numbers of associahedra and some others interestingmembers of the family of nestohedra.
