Abstract. In the study of Zeilberger's conjecture on an integer sequence related to the Catalan numbers, Lassalle proposed the following conjecture.
Jun 15, 2017 · As the title says, what methods exists for proving that a symmetric polynomial (or function) is Schur positive, perhaps involving extra parameters.
Schur positivity conjectures. The ring of symmetric functions has a linear basis of Schur functions sλ labelled by partitions λ = (λ1 ≥ λ2 ≥ททท≥ 0),.
We would like to prove that the following entities are Schur-positive symmetric functions. Ideally, the proofs would also yield explicit combinatorial and/or ...
Sep 1, 2012 · In this section, we prove the following theorem on the positivity of the spe- cialization of skew Schur functions. It is clear that Lassalle's ...
