| Part I : Curves
Curves: Parametrized and regular curves, arc length, parametrization by arc length. Local Theory: Tangent-normal-binormal frame, curvature, torsion, fundamental theorems of local theory of plane and space curves. Global Theory: Simple curves, Jordan curve theorem (without proof), isoperimetric in-equality, four-vertex theorem. Part II : Surfaces Surfaces: Parametrization, change of parameters, smooth functions, tangent plane, differential, diffeomorphism, inverse and implicit function theorems. Second Fundamental Form and Curvature: Gauss map; oriented surfaces; second fundamental form; Gauss, mean and principal curvatures; normal sections. Integration on Surface: Definition of integral, partitions of unity, change of variables formula, divergence theorem. Geometry of Surfaces: Rigid motions and isometries, Gausss Theorema Egregium, geodesics. Gauss-Bonnet Theorem : Index of a vector field at an isolated zero, Euler characteristic (if time permits). |
