Combinatorics of r-Dyck paths, r-Parking functions, and the r-Tamari lattices

Abstract

This paper's aim is to present recent combinatorial considerations on r-Dyck paths, r-Parking functions, and the r-Tamari lattices. Giving a better understanding of the combinatorics of these objects has become important in view of their (conjectural) role in the description of the graded character of the Sn-modules of bivariate and trivariate diagonal coinvariant spaces for the symmetric group.Comment: 36 pages, 12 figure
