| title = On the combinatorics of several integrable hierarchies
| abstract = We establish a correspondence between the generating functions related to some integrable hierarchies and certain classes of set partitions. In a sense, the inverse problem of enumerative combinatorics is considered: given a prescribed statistics, to figure out a definition of the corresponding combinatorial objects. The answer for the potential Burgers hierarchy is rather well known: set partitions, Bell polynomials, Stirling numbers of the 2nd kind, Bell numbers. An analogous correspondence for the KdV hierarchy (non-overlapping partitions, Bessel numbers) and Ibragimov–Shabat hierarchy (B type partitions, Dowling numbers) is new.
