On Sums, Derivatives, and Flips of Riordan Arrays
Caroline Bang, Matias von Bell, Eric Culver +4
We study three operations on Riordan arrays. First, we investigate when the sum of Riordan arrays yields another Riordan array. We characterize the - and -sequences of these…
On the subdivision algebra for the polytope
Matias von Bell, Martha Yip
The polytopes were introduced by Ceballos, Padrol, and Sarmiento to provide a geometric approach to the study of -Tamari lattices. They obser…
A unifying framework for the -Tamari lattice and principal order ideals in Young's lattice
Matias von Bell, Rafael S. González D'León, Francisco A. Mayorga Cetina +1
We present a unifying framework in which both the -Tamari lattice, introduced by Préville-Ratelle and Viennot, and principal order ideals in Young's lattice indexed by lattice p…
Schroder combinatorics and -associahedra
Matias von Bell, Martha Yip
We study -Schröder paths, which are Schröder paths which stay weakly above a given lattice path . Some classical bijective and enumerative results are extended to the -set…
