Résumé :
There is the same number of $n \times n$ alternating sign matrices (ASMs) as there is of descending plane partitions (DPPs) with parts no greater than $n$, but finding an explicit bijection is, despite many efforts, an open problem for about $40$ years now. So far, four pairs of statistics that have the same joint distribution have been identified. We introduce extensions of ASMs and of DPPs along with $n+3$ pairs of statistics that have the same joint distribution. The ASM-DPP equinumerosity is obtained as an easy consequence by considering the $(-1)$enumerations of these extended objects with respect to one pair of the $n+3$ pairs of statistics. One important tool of our proof is a multivariate generalization of the operator formula for the number of monotone triangles with prescribed bottom row that generalizes Schur functions. Joint work with Florian Aigner.
