Resumen de A note about isothermic surfaces in Rn−j,j

M P Dussan, M. A. Magid

• ABSTRACT In this note we survey our results on the description of ti-melike isothermic surfaces in Rn-j,j using the Grassmannian systems or U/K-systems. We give the natural extensions of the definition of Ribaucour and Darboux transformations for timelike isothermic surfaces and review how those transformations correspond to dressing actions of suitable simple elements.
