A note on W–algebra Realisations
نویسنده
چکیده
We provide a general description of realisations of W–algebras in terms of smaller W–algebras and free fields. This is based on the definition of the W–algebra as the commutant of a set of screening charges. This is conjectured to be related to partial gauge-fixings in the Hamiltonian reduction model.

Embedding of the Bosonic String into the W 3 String
We investigate new realisations of the W 3 algebra with arbitrary central charge, making use of the fact that this algebra can be linearised by the inclusion of a spin-1 current. We use the new realisations with c = 102 and c = 100 to build non-critical and critical W 3 BRST operators. Both of these can be converted by local canonical transformations into a BRST operator for the Virasoro string...
متن کاملRealisations of W3 Symmetry
We perform a systematic investigation of free-scalar realisations of the Zamolodchikov W 3 algebra in which the operator product of two spin-three generators contains a non-zero operator of spin four which has vanishing norm. This generalises earlier work where such an operator was required to be absent. By allowing this spin-four null operator we obtain several realisations of the W 3 algebra ...
متن کاملAnomaly Freedom and Realisations for Super - W 3 Strings
We construct new multi-field realisations of the N = 2 super-W 3 algebra, which are important for building super-W 3 string theories. We derive the structure of the ghost vacuum for such theories, and use the result to calculate the intercepts. These results determine the conditions for physical states in the super-W 3 string theory.
متن کاملA Note on Spectrum Preserving Additive Maps on C*-Algebras
Mathieu and Ruddy proved that if be a unital spectral isometry from a unital C*-algebra Aonto a unital type I C*-algebra B whose primitive ideal space is Hausdorff and totallydisconnected, then is Jordan isomorphism. The aim of this note is to show that if be asurjective spectrum preserving additive map, then is a Jordan isomorphism without the extraassumption totally disconnected.
متن کاملHigher - spin Realisations of the Bosonic String
It has been shown that certain W algebras can be linearised by the inclusion of a spin–1 current. This provides a way of obtaining new realisations of the W algebras. Recently such new realisations of W3 were used in order to embed the bosonic string in the critical and non-critical W3 strings. In this paper, we consider similar embeddings in W2,4 and W2,6 strings. The linearisation of W2,4 is ...
