GEOMETRIA DIFFERENZIALE

Differential Geometry studies geometrical objects like curves, surfaces and manifolds using the tools of mathematical analysis. The course aims to introduce the basics of the theory of differentiable manifolds both in its global and local aspects. We will also study Riemannian manifolds, focusing on curves and surfaces in Euclidean space.

There will be lectures and exercise sets. Students may be invited to present their solution to some of the exercises at the blackboard.

1. Survey of general topology and multilinear algebra.
2. Topological and differential manifolds.
3. The tangent space and vector fields.
4. Tensors in tangent space, tensor fields.
5. The external derivative.
6. Curves in space, arclength, curvature, torsion.
7. Parametrical surfaces, First and Second fundamental form, gaussian curvature and Teorema Egregium, geodetics.
8. Linear connection and Riemannian varieties.
