normal curvature vector

This paper uses parametric quinary Bézier curve to interpolate a given special curve, whose position, tangent direction, curvature vector and torsion are prescribed at each endpoint.

在给定空间曲线两个端点的位置、切方向、曲率向量和挠率的情况下 ,用参数化五次B啨ｚｉｅｒ曲线来对这条空间曲线进行几何Hermite插值 ,证明了插值问题局部可解 ,解有两个自由度 ,还给出了一种确定这两个自由度的方法 ;并证明了在适当的假设下插值有 6阶逼近

In the first part, we consider the compact totally real pseudoumbilical submanifolds Mn that have nonzero parallel normalized mean curvature vector in complex space forms M(n+p)(c).
