| Jun 1, 2023 at 6:18 | comment | added | Tom Copeland | The combinatorial import of the inverse series is evident from the combinatorial models for compositional inversion via A133437 and OEIS A134264, e.g., associahedra and noncrossing partitions. | |
| Jun 1, 2023 at 1:59 | comment | added | Tom Copeland | The inverse series $y(x) = x-x^k= x(1-x^{k-1})$ is the compositional inverse of the invertible o.g.f. of aerated (k)-Fuss-Catalan sequences with the Catalans corresponding to $k=2$. See, e.g., oeis.org/A001764. Proofs usually simplify using this observation or by resorting to a higher algebra of sets of partition polynomials for which the Fuss-Catalan sequences are 'diagonal' coefficients. | |
