ED标架下的类法曲线
Normal-Like Curves According to the ED-Frame in E41
摘要
Abstract
Based on the extended Darboux(ED)-framework,the normal-like curves under a specific ED-frame in E4 is defined.The concept of normal curves is extended to E41,and the characteristics of normal-like curves are analyzed in depth.Three equations relating the curvature of normal curves on hypersur-faces M are derived.These equations serve as the necessary and sufficient conditions for normal-like curves in E41.By applying the ED-frame,we define the E-expressions in E41 and give concrete applica-tion examples.关键词
