Abstract

Let λ=(λ1λk>0)\lambda=(\lambda_1 \geqslant \ldots \geqslant \lambda_k > 0). For any cc Coxeter element of Sλ1+k1\mathfrak{S}_{\lambda_1+k-1}, we construct a bijection from fillings of λ\lambda to reverse plane partitions. We recover two previous generalizations of the Robinson--Schensted--Knuth correspondence for particular choices of Coxeter element depending on λ\lambda: one based on the work of, among others, Burge, Hillman, Grassl, Knuth, and uniformly presented by Gansner; the other developed by Garver, Partrias, and Thomas, and independently by Dauvergne, called Scrambled RSK. Our results in this paper develop the combinatorial consequence of our previous work of type Aλ1+kA_{\lambda_1+k} quivers.
