| Aims |
|
The course gives to the students the principal tools and also the necesary methods in the study of curves and surfaces with an accent on the intuitive side. |
| Content |
|
I. Local theory of curves.
1. Curves in euclidean space.Tangent line and normal plane. 2. Curves in general position. Osculating plane. 3. Frenet frame. Frenet formulas. Curvature and torsion. 4. Geometric iterpretation of curvature and torsion. 5. Contact beatween two curves. 6. Evolute and involute. 7. Envelope of a family of curves in plane. II.Local theory of surfaces. 1. Surfaces in three-dimensional euclidean space. 2. Tangent plane and normal line of a surface. 3. First fundamental form of a surface. 4. Arc length , angle between two curves on surface .Area element. 5. Second fundamental form. 6. Normal curvature. 7. Asymptotic lines of a surface. 8. Principal curvatutres of a surface.
