My question is prompted by Ben Webster's [answer][1] to [this question][2].

**Is there a notion of tensor product for representations of a finite W-algebra?**

I thought about this question years ago in the context of the infinite-dimensional W-algebras in conformal field theory, but failed to reach a satisfactory conclusion.  I was hoping that now that the professional representation theorists have started to study finite W-algebras an answer might be forthcoming.
