Brick polytopes, lattices and Hopf algebras [PDF]
Discrete Mathematics & Theoretical Computer Science, 2020 Generalizing the connection between the classes of the sylvester congruence and the binary trees, we show that the classes of the congruence of the weak order on Sn defined as the transitive closure of the rewriting rule UacV1b1 ···VkbkW ≡k UcaV1b1 ...

A Tropical Intersection Product in Matroidal Fans [PDF]
SIAM Journal on Discrete Mathematics, 2013 We construct an intersection product on tropical cycles contained in the Bergman fan of a matroid. To do this we first establish a connection between the operations of deletion and restriction in matroid theory and tropical modifications as defined by Mikhalkin.

Fans and Bundles in the Graph of Pairwise Sums and Products [PDF]
The Electronic Journal of Combinatorics, 2004 Let $G^{\times}_{+}$ be the graph on the vertex-set the positive integers ${\Bbb{N}}$, with $n$ joined to $m$ if $n\neq m$ and for some $x,y\in{\Bbb{N}}$ we have $x+y=n$ and $x\cdot y=m$. A pair of triangles sharing an edge (i.e., a $K_4$ with an edge deleted) and containing three consecutive numbers is called a $2$-fan, and three triangles on five ...
