Title A NOTE ON RIBAUCOUR TRANSFORMATIONS IN LIE SPHERE GEOMETRY

Author Jianquan Ge

(Received December 20, 2013, revised April 8, 2014)
Abstract. Following Burstall and Hertrich-Jeromin we study the Ribaucour transformation of Legendre submanifolds in Lie sphere geometry. We give an explicit parametrization of the resulted Legendre submanifold $\hat{F}$ of a Ribaucour transformation, via a single real function $\tau$ which represents the regular Ribaucour sphere congruence $s$ enveloped by the original Legendre submanifold $F$.
