Strong coupling limit of open string: Born-Infeld analysis - art. no. 081901

We consider a large coupling limit of a Born-Infeld action in a curved back ground of an arbitrary metric and a two form field. Following Gibbons. Hori , and Yi, we go to the Hamiltonian description. The Hamiltonian can be dual ized and the dual action admits a stringlike configuration as its solution. We interpret it as a closed string configuration. The procedure can be vie wed as a novel way of bringing out the appropriate degrees of freedom, a cl osed string, for an open string under the strong coupling limit. We argue t hat this interpretation implies a large number of dual pairs of gauge and g ravity theories whose particular examples are AdS/CFT and matrix theory con jectures.
