Abstract

We study the Gnedin-Kingman graph, which corresponds to Pieri's rule for the monomial basis {Mλ}\{M_{\lambda}\} in the algebra QSym\mathrm{QSym} of quasisymmetric functions. The paper contains a detailed announcement of results concerning the classification of indecomposable semifinite harmonic functions on the Gnedin-Kingman graph. For these functions, we also establish a multiplicativity property, which is an analog of the Vershik-Kerov ring theorem.
