| Abstract: | By relating the two-dimensional U(N) Principal Chiral Model to a simple linear system we obtain a free-field parametrisation of solutions. Obvious symmetry transformations on the free-field data give symmetries of the model. In this way all known “hidden symmetries” and B?cklund transformations, as well as a host of new symmetries, arise. Received: 20 November 1996 / Accepted: 25 April 1997 |
