11 Jul 1992 | | Journal: | Mod.Phys.Lett. A7 (1992) 2753-2762 | | Abstract: | The KdV and modified KdV integrable hierarchies are shown to be different descriptions of the same 2D gravitational system -- open-closed string theory. Non-perturbative solutions of the multi-critical unitary matrix models map to non-singular solutions of the `renormalisation group’ equation for the string susceptibility, $[ ilde{P},Q]=Q$. We also demonstrate that the large N solutions of unitary matrix integrals in external fields, studied by Gross and Newman, equal the non-singular pure closed-string solutions of $[ ilde{P},Q]=Q$. | | Source: | arXiv, hep-th/9206060 | | Services: | Forum | Review | PDF | Favorites | |
