A Derivation of the BRST Operator for Non-Critical W-Strings

E. Bergshoeff, A. Sevrin, X. Shen

We derive the recently proposed BRST charge for non-critical W strings from a Lagragian approach. The basic observation is that, despite appearances, the combination of two classic…

W-Infinity and String Theory

X. Shen

We review some recent developments in the theory of $W_{\infty}$ . We comment on its relevance to lower-dimensional string theory.

$S L (\infty, R)$ Symmetry of $W_{\infty}$ Gravity

C. N. Pope

Two-dimensional gravity in the light-cone gauge was shown by Polyakov to exhibit an underlying $S L (2, R)$ Kac-Moody symmetry, which may be used to express the energy-momentum tensor…
