Diameter of the commutation classes graph of a permutation
G. Gutierres, R. Mamede, J. L. Santos
We define a statistic on the graph of commutation classes of a permutation of the symmetric group which is used to show that these graphs are equipped with a ranked poset structure…
A classification of monotone ribbons with full Schur support with application to the classification of full equivalence classes
Olga Azenhas, Ricardo Mamede
We consider ribbon shapes, not necessarily connected, whose rows, with at least two boxes in each, are in monotone length order. These ribbons are uniquely defined by a pair of par…
Multiplicity-free Skew Schur functions with full interval support
Olga Azenhas, Alessandro Conflitti, Ricardo Mamede
It is known that the Schur expansion of a skew Schur function runs over the interval of partitions, equipped with dominance order, defined by the least and the most dominant Little…
On Noncrossing and nonnesting partitions of type D
Alessandro Conflitti, Ricardo Mamede
We present an explicit bijection between noncrossing and nonnesting partitions of Coxeter systems of type D which preserves openers, closers and transients.
Linear time equivalence of Littlewood--Richardson coefficient symmetry maps
Olga Azenhas, Alessandro Conflitti, Ricardo Mamede
Benkart, Sottile, and Stroomer have completely characterized by Knuth and dual Knuth equivalence a bijective proof of the conjugation symmetry of the Littlewood-Richardson coeffici…
A bijection between noncrossing and nonnesting partitions of types A and B
Ricardo Mamede
The total number of noncrossing partitions of type is the th Catalan number when , and the binomial when , and…
