Query: Orbifolds and Finite Group Representations   We present our recent understanding on resolutions of Gorenstein orbifolds,
which involves the finite group representation theory. We shall concern only
the quotient singularity of hypersurface type. The abelian group $A_r(n)$ for
$A$-type hypersurface quotient singularity of dimension $n$ is introduced. For
$n=4$, the structure of Hilbert scheme of group orbits and crepant resolutions
of $A_r(4)$-singularity are obtained. The flop procedure of 4-folds is
explicitly constructed through the process.
