Abstract: 
The N=2 superconformal algebra (SCA) is an infinitedimensional Lie
superalgebra which is obtained as a supersymmetric generalization of the
Virasoro algebra.
The representation theory of the N=2 SCA involves several remarkable topics,
for example, the (mock) modular property of characters and the braided
tensor structure with respect to the fusion product.
B. Feigin, A. Semikhatov and I. Tipunin discovered that general highest
weight modules over the N=2 SCA correspond to certain nonstandard highest
weight modules over via the KazamaSuzuki coset
construction.
In this talk, we give (blockwise) equivalences between the categries of
certain weight modules over and the N=2 SCA by refining
their work.
