Enumerative combinatorics related to partition shapes (2008)
Jonas Sjöstrand, Kungl Tekniska Högskolan
This thesis deals with enumerative combinatorics applied to three different objects related to partition shapes, namely tableaux, restricted words, and Bruhat intervals. The main scientific...
From Bruhat intervals to intersection lattices and a conjecture of Postnikov (2007)
Hultman, Axel, Linusson, Svante, Shareshian, John, Sjöstrand, Jonas
We prove the conjecture of A. Postnikov that (A) the number of regions in the inversion hyperplane arrangement associated with a permutation $w\in \Sn$ is at most the number of elements below $w$ in...

Bier Spheres and Posets (2004)
Anders Björner, Anders Bj Orner, Jonas Sjöstrand, Andreas Paffenholz, Jonas Sj Ostrand, Günter M. Ziegler, ...
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 with its...

On the sign-imbalance of partition shapes (2003)
Let the sign of a standard Young tableau be the sign of the permutation you get by reading it row by row from left to right, like a book. A conjecture by Richard Stanley says that the sum of the...
