# Bijections of Littlewood-Richardson coefficients

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?

• I found two papers that might be helpful: doi.org/10.1137/17M1162834, mathscinet.ams.org/mathscinet-getitem?mr=1773572. Jan 24, 2020 at 4:57
• Do you know how to download the first one ? I can not do this. Jan 24, 2020 at 9:46
• Sci-Hub helps with the first one. Also, there is a preprint. Moreover, see this (not the same paper). Jan 24, 2020 at 12:54
• thank you so much Darij! Jan 29, 2020 at 12:13
