Let $c^{\lambda}_{\mu\nu}$ be the Littlewood-Richardson coefficients, where $\lambda,\mu,\nu$ are partitions. We know that $c^{\lambda}_{\mu\nu}= c^{\lambda}_{\nu\mu}$. Up to now, what are the bijections we known to prove this equality?

$\begingroup$ Do you know how to download the first one ? I can not do this. $\endgroup$– MihawkJan 24, 2020 at 9:46

2$\begingroup$ Sci-Hub helps with the first one. Also, there is a preprint. Moreover, see this (not the same paper). $\endgroup$– darij grinbergJan 24, 2020 at 12:54
