摘要 本文介绍了Anti de Sitter 2-空间中类时曲线的Anti de Sitter渐屈线的概念,利用具有Anti de Sitter双曲线的类时曲线的切触几何方法,本文也研究了上述空间中渐屈线奇点的几何意义. We introduced the notion of Anti de Sitter evolutes of timelike curves in Anti de Sitter 2-space and investigated the geometric meanings of singularities of the evolutes in terms of the contact of the timelike curves with Anti de Sitter hyperbola.
