Chain polynomials of distributive lattices are 75 % unimodal
Anders Björner, Jonathan David Farley
It is shown that the numbers of chains of length in the proper part of a distributive lattice of length satisfy the inequalities $$c_0<.…
A note on blockers in posets
Anders Björner, Axel Hultman
The blocker of an antichain in a finite poset is the set of elements minimal with the property of having with each member of a common predecessor. The following…
Geometrically constructed bases for homology of partition lattices of types A, B and D
Anders Björner, Michelle L. Wachs
We use the theory of hyperplane arrangements to construct natural bases for the homology of partition lattices of types A, B and D. This extends and explains the "splitting basis"…
Bier spheres and posets
Anders Björner, Andreas Paffenholz, Jonas Sjöstrand +1
In 1992 Thomas Bier presented a strikingly simple method to produce a huge number of simplicial (n-2)-spheres on 2n vertices as deleted joins of a simplicial complex on n vertices…
