  A theorem of Y. Berest, P. Etingof and V. Ginzburg states that finite
dimensional irreducible representations of a type A rational Cherednik algebra
are classified by one rational number m/n. Every such representation is a
representation of the symmetric group S_n. We compare certain multiplicity
spaces in its decomposition into irreducible representations of S_n with the
spaces of differential forms on a zero-dimensional moduli space associated with
the plane curve singularity x^m=y^n.
