论文摘要
这些笔记是为计划在差异几何形状上工作的人设计的，或者至少希望有充分的理由不这样做。我们讨论平滑的曲线和表面 - 差分几何形状的主要门。我们专注于对进一步研究，使其以问题为中心，基础，视觉和几乎严格的技术。
These notes are designed for those who either plan to work in differential geometry, or at least want to have a good reason not to do it. We discuss smooth curves and surfaces -- the main gate to differential geometry. We focus on the techniques that are absolutely essential for further study, keeping it problem-centered, elementary, visual, and virtually rigorous.
