Extended Superconformal Algebras from Classical and Quantum Hamiltonian Reduction

K. Ito, J. O. Madsen, J. L. Petersen

We consider the extended superconformal algebras of the Knizhnik-Bershadsky type with $W$ -algebra like composite operators occurring in the commutation relations, but with generato…

Free Field Representations and Screening Operators for the $N = 4$ Doubly Extended Superconformal Algebras

Katsushi Ito, Jens Ole Madsen, Jens Lyng Petersen

We present explicit free field representations for the $N = 4$ doubly extended superconformal algebra, $A ~_{γ}$ . This algebra generalizes and contains all previous $N = 4$ s…

Free Field Representations of Extended Superconformal Algebras

Katsushi Ito, Jens Ole Madsen, Jens Lyng Petersen

We study the classical and quantum $G$ extended superconformal algebras from the hamiltonian reduction of affine Lie superalgebras, with even subalgebras $G \oplus s l (2)$ . At the cl…
