Query: Quantum reduction in the twisted case   We study the quantum Hamiltonian reduction for affine superalgebras in the
twisted case. This leads to a general representation theory of all
superconformal algebras, including the twisted ones (like the Ramond algebra).
In particular, we find general free field realizations and determinant
formulae.
