摘要
We show that space-like isothermic surfaces in the pseudo-riemannian space R-n-j,R-j are associated to O(n - j + 1, j + 1) / O(n - j, j) x O(1, 1)-system, and that the action of a rational map with two simple poles on the space of local solutions of O(n - j + 1, j + 1) / O(n - j, j) x O(1, 1)-system correspond to Ribaucour and Darboux transformations to space-like surfaces in R-n-j,R- j.
