課程概述 |
Applying basic calculus and linear algebra to study the surface inside 3 dimensional space gives fruitful results and forms the basis of modern differential geometry, which, in turns, provide the framework of general relativity and quantum field theory.
Our course would concentrate on the concept of "curvature", "surface" and the interplay between them. We shall conduct a course from the local behavior of a surface to the global property of it. |
課程目標 |
1. Curvature of Curves.
2. Curvature of Surfaces.
3. Internal Curvature of Surfaces.
4. Curvature and Global Property of Surfaces |
