Abstract: We give a conceptual proof that the Poincar\-e series of the coordinatealgebra of a Kleinian singularity and of a Fuchsian singularity of genus 0 isthe quotient of the characteristic polynomials of two Coxeter elements. TheseCoxeter elements are interpreted geometrically, using triangulated categoriesand spherical twist functors.
