Ao. Garcia et Rc. Trinchero, CONSTRUCTIVE BUILDING OF THE LAX PAIR IN THE NONLINEAR SIGMA-MODEL, Journal of mathematical physics, 37(8), 1996, pp. 3973-3981
A derivation of the Lax pair for the (1+1)-dimensional non-linear sigm
a-model is described. Its main benefit is to have a clearer physical o
rigin and to allow the study of a generalization to higher dimensions.
