Abstract

Functional equations with one catalytic variable appear in several combinatorial applications, most notably in the enumeration of lattice paths and in the enumeration of planar maps. The main purpose of this paper is to show that under certain positivity assumptions, the dominant singularity of the solution has a universal behavior. We have to distinguish between linear catalytic equations, where a dominating square root singularity appears, and non-linear catalytic equations, where we—usually—have a singularity of type 3/2.

Notes

  1. In [6], an additional additive polynomial term \(F_0(z,u)\) is considered, however, by substituting M(zu) by \(M(z,u)-F_0(z,u)\) the seemingly more general case can be reduced to the case (4).
