The Pelletier--Ressayre hidden symmetry for Littlewood--Richardson coefficients

Published Web Location Commons 'BY' version 4.0 license

We prove an identity for Littlewood--Richardson coefficients conjectured by Pelletier and Ressayre. The proof relies on a novel birational involution defined over any semifield.

Keywords: Symmetric functions, Littlewood--Richardson coefficients, partitions, Schur functions, Schur polynomials, birational combinatorics, detropicalization, partitions.
