On the Counting of Fully Packed Loop Configurations. Some new conjectures

open access: yes, 2003
New conjectures are proposed on the numbers of FPL configurations pertaining to certain types of link patterns. Making use of the Razumov and Stroganov Ansatz, these conjectures are based on the analysis of the ground state of the Temperley-Lieb chain ...

Bubble Lattices II: Combinatorics

Annals of Combinatorics, 2022
We introduce two simplicial complexes, the noncrossing matching complex and the noncrossing bipartite complex. Both complexes are intimately related to the bubble lattice introduced in our earlier article"Bubble Lattices I: Structure"(arXiv:2202.02874 ...

On higher partial derivatives of implicit functions and their combinatorics

Online Journal of Analytic Combinatorics, 2022
We consider a scalar-valued implicit function of many variables, and provide two closed formulae for all of its partial derivatives. One formula is based on products of partial derivatives of the defining function, the other one involves fewer products ...

Signed combinatorial interpretations in algebraic combinatorics

Algebraic Combinatorics
We prove the existence of signed combinatorial interpretations for several large families of structure constants. These families include standard bases of symmetric and quasisymmetric polynomials, as well as various bases in Schubert theory.
