WebClearly, if any Z-graded weak module is completely reducible, then the vertex operator algebra is rational. So it remains to prove that if any Z-graded weak module is completely reducible for a vertex operator algebra V, then V is C2-cofinite. It is well known that the graded dual V′ of V is also a V-module [FHL]. By a result from [L], if L ... WebIn this case, we call V a g-module. Example 1.2.
