 Ribaucour transformations of the Surfaces with constant positive Gaussian curvatures in the 3-dimensional Euclidean space Commun. Korean Math. Soc. 2006 Vol. 21, No. 1, 165-175 Printed March 1, 2006 Joonsang Park Dongguk University Abstract : We associate the surfaces of constant Gaussian curvature $K=1$ with no umbilics to a subclass of the solutions of $O(4,1)/O(3)\times O(1,1)$-system. From this correspondence, we can construct new $K=1$ surfaces from a known $K=1$ surface by using a kind of dressing actions on the solutions of this system. Keywords : Gaussian curvature, sinh-Gordon equation, $G/K$-system, flat connection, sphere congruence, Ribaucour transformation MSC numbers : 57N35 Downloads: Full-text PDF
