The $W$ algebra structure of $N = 2$ $C P_{n}$ coset models

Katsushi Ito

We discuss the $N = 2$ super $W$ algebras from the hamiltonian reduction of affine Lie superalgebras $A (n ∣ n - 1)^{(1)}$ and $A (n ∣ n)^{(1)}$ . From the quantum hamiltonian reduction of $A…

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…

Hamiltonian Reduction and Classical Extended Superconformal Algebras

Katsushi Ito, Jens Ole Madsen

We present a systematic construction of classical extended superconformal algebras from the hamiltonian reduction of a class of affine Lie superalgebras, which include an even suba…
