The Poincaré Series of Some Special Quasihomogeneous Surface Singularities

Wolfgang Ebeling[1]

(1) Universität Hannover, Germany

In [E6] a relation is proved between the Poincaré series of the coordinate algebra of a two-dimensional quasihomogeneous isolated hypersurface singularity and the characteristic polynomial of its monodromy operator. We study this relation for Fuchsian singularities and show that it is connected with the mirror symmetry of K3 surfaces and with automorphisms of the Leech lattice. We also indicate relations between other singularities and Conway’s group.
