Geometria Diferencial de Curvas e Superfícies - Aula 07

Explore a comprehensive lecture on Differential Geometry of Curves and Surfaces in this seventh installment of a master's level course taught by Professor Lucas Ambrozio. Delve into advanced topics such as curves in plane and space, length, curvature, and torsion. Examine surfaces in R3, including their definitions, parameterizations, and coordinate changes. Study the first fundamental form, distances, areas, and curvature. Investigate the Gauss normal map, second fundamental form, principal curvatures, Gaussian curvature, and mean curvature. Learn about curvature lines, asymptotic lines, and the significance of Gaussian curvature's sign. Discover the relationship between mean curvature and area, and explore important theorems like the sphere rigidity theorem and Alexandrov's theorem. Compare intrinsic and extrinsic geometry, and understand isometries and Gauss's Theorema Egregium. Delve into covariant derivatives, parallel transport, geodesic curvature, and geodesics. Examine the Gauss-Bonnet theorem and its applications, along with other global theorems and related topics.
