(Elsevier B.V., 2019)
In the early 1990s, a family of combinatorial CW-complexes named permutoassociahedra was introduced by Kapranov, and it was realised by Reiner and Ziegler as a family of convex polytopes. The polytopes in this family are ...
Syntactic aspects of hypergraph polytopes
(Springer, 2019)
This paper introduces an inductively defined tree notation for allthe faces of polytopes arising from a simplex by truncations. This notation al-lows us to view inclusion of faces as the process of contracting tree edges. ...
