A combinatorial model for the canonical join complex of alt -Tamari lattices
Matthias Müller
The paper introduces a combinatorial model for the canonical join complex of alt ν‑Tamari lattices and uses it to prove vertex decomposability, give an explicit shelling order, and…

Geometric realizations of -associahedra via brick polyhedra
Cesar Ceballos, Matthias Müller
Brick polytopes constitute a remarkable family of polytopes associated to the spherical subword complexes of Knutson and Miller. They were introduced for finite Coxeter groups by P…
