ABSTRACT

For kleinian singularity, there exits the mckay correspondence among binary polyhedral groups, the extended cdw-diagrams and the set of isomorphism classes of non trivial indecomposable reflexive modules. (artin and gonzales-sprinberg, artin and verdier, and esnault)

J. wunram [1-8] generalized the result to quotient surface singularities. this work has a connection with constructing the deformation. ( riemenschneider [5])

In the present paper, we define special reflexive modules in the cases which need numerical experiences in addition to wunram algorithm.
