30 Apr 1998 | Journal: | Chaos Solitons Fractals 10 (1999) 385-397 | Subject: | hep-th | Abstract: | We review some aspects of the construction of self-dual gravity and the associated field theory of ${cal N}=2$ strings in terms of two-dimensional sigma models at large $N$. The theory is defined through a large $N$ Wess-Zumino-Witten model in a nontrivial background and in a particular double scaling limit. We examine the canonical structure of the theory and describe an infinite-dimensional Poisson algebra of currents. | Source: | arXiv, hep-th/9804206 | Services: | Forum | Review | PDF | Favorites |
