Query: On Representations of Classical Groups over Finite Local Rings of Length
  Two   We study the complex irreducible representations of special linear,
symplectic, orthogonal and unitary groups over principal ideal local rings of
length two. We construct a canonical correspondence between the irreducible
representations of all such groups that preserves dimensions. The case for
general linear groups has already been proved by author.
