Title: | Multiplicity-free skew Schur functions with full interval support | Authors: | Azenhas, Olga Conflitti, Alessandro Mamede, Ricardo |
Issue Date: | 2019 | Project: | UID/MAT/00324/2013 | Serial title, monograph or event: | Séminaire Lotharingien de Combinatoire | Volume: | 75 | Issue: | Article B75j | Abstract: | 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 Littlewood-Richardson filling of the skew shape. We characterise skew Schur functions (and therefore the product of two Schur functions) which are multiplicity-free and the resulting Schur expansion runs over the whole interval of partitions, i.e., skew Schur functions having Littlewood-Richardson coefficients always equal to 1 over the full interval. | URI: | https://hdl.handle.net/10316/89667 | Rights: | openAccess |
