MATH-213 / 5 crédits

Enseignant: Moschidis Georgios

Langue: Anglais


Summary

This course serves as an introduction to classical differential geometry, which studies the geometric properties of curves and surfaces in the Euclidean space.

Content

  • Curves in the Euclidean plane and the Euclidean space.
  • The notion of submanifolds of Euclidean space, charts, local parametrizations, the tangent space.
  • The metric tensor (first fundamental form) of a parametrized surface.
  • Curvature of regular surfaces (second fundamental form, Gaussian curvature, mean curvature, principal curvatures).
  • Isometric surfaces. Gauss's Theorema Egregium.
  • Notions of hyperbolic geometry.
  • A short introduction to notions of abstract manifolds.

Keywords

Curves, surfces, submanifolds, curvature, torsion, geodesics, first/second fundamental form, differential geometry, hyperbolic geometry.
