Ptolemy diagrams and torsion pairs in the cluster category of Dynkin type A_n
Thorsten Holm, Peter Jorgensen, Martin Rubey
We give a complete classification of torsion pairs in the cluster category of Dynkin type A_n. Along the way we give a new combinatorial description of Ptolemy diagrams, an infinit…
Maximal 0-1 fillings of moon polyominoes with restricted chain-lengths and rc-graphs
Martin Rubey
We show that maximal 0-1-fillings of moon polynomials with restricted chain lengths can be identified with certain rc-graphs, also known as pipe dreams. In particular, this exhibit…
Crossings, Motzkin paths and Moments
Matthieu Josuat-Vergès, Martin Rubey
Kasraoui, Stanton and Zeng, and Kim, Stanton and Zeng introduced certain -analogues of Laguerre and Charlier polynomials. The moments of these orthogonal polynomials have combin…
The number of ribbon Schur functions
Martin Rubey
We present a formula for the number of distinct ribbon Schur functions of given size and height.
