N=1 and N=2 cosets from gauged supersymmetric WZW models
Jose M Figueroa-O'Farrill, Sonia Stanciu
We present a derivation of the N=1 and N=2 superconformal coset constructions starting from a supersymmetric WZW model where a diagonal subgroup has been gauged. We work in the gen…
On the structure of symmetric self-dual Lie algebras
JM Figueroa-O'Farrill, S Stanciu
A finite-dimensional Lie algebra is called (symmetric) self-dual, if it possesses an invariant nondegenerate (symmetric) bilinear form. Symmetric self-dual Lie algebras have been s…
Nonreductive WZW models and their CFTs
JM Figueroa-O'Farrill, S Stanciu
We study two-dimensional WZW models with target space a nonreductive Lie group. Such models exist whenever the Lie group possesses a bi-invariant metric. We show that such WZW mode…
Lie-Poisson groups and the Miura transformation
JM Figueroa-O'Farrill, S Stanciu
We point out that the recent proof of the Kupershmidt-Wilson theorem by Cheng and Mas-Ramos is underpinned by the Lie-Poisson property of the second Gel'fand-Dickey bracket. The su…
