| Summary:
There are many generalizations of the McKay correspondence for higher
dimensional Gorenstein quotient singularities and there are some applications
to compute the topological invariants today. But some of the invariants are
completely different from the classical invariants, in particular for
non-Gorenstein cases. In this paper, we would like to discuss the McKay
correspondence for 2-dimensional quotient singularities via "special"
representations which gives the classical topological invariants and give a new
characterization of the special representations for cyclic quotient
singularities in terms of combinatorics.
