The course introduces and elaborates the fundamental ideas of general topology and of the differential geometry of curve and surfaces, in a rigorous yet concrete and
example-based manner, so as to further develop the students' geometric intuition,
abstraction and analytical computing ability, also in view of applications to parallel and successive courses.
Topological spaces, continuous functions, omeomorphisms.
Plane and spatial curves: curvature, torsion, Fre'net's formulae. Fundamental theorem.
Regular parametric surfaces. First and second fundamental form.
Gaussian and mean curvature.
Gauss' Theorema Egregium. Covariant derivative, parallel transport.
Geodesics. The Gauss-Bonnet theorem.
Examples: quadrics, surfaces of revolution, ruled and minimal surfaces.
Projective, affine and metric classification of quadrics.
Written test, followed by an oral exam.
