Abstract:
We discuss new realisations of algebras in which the currents are expressed in terms of two arbitrary commuting energy-momentum tensors together with a set of free scalar fields. This contrasts with the previously-known realisations, which involve only one energy-momentum tensor. Since realisations of non-linear algebras are not easy to come by, the fact that this new class exists is of intrinsic interest. We use these new realisations to build the corresponding -string theories and show that they are effectively described by two independent ordinary Virasoro-like strings.- algebra: W(N)
