Learning outcomes
A student:
1. Understands notions of a submanifold, tangent vectors and differential of a smooth map.
2. Understands geometric sense of the normed parametrization of a curve, and of its curvature and torsion.
3. Understands difference between external and intrinsic properties of submanifolds.
4. Is able to recognize points of negaitive, ositive and zero Gauss curvature on a surface and knows that the Gauss curvature is an intrinsic invariant.
5. Is able to give examples of geodesics and knows that they are invariant under isometries.
6. Is able to describe examples of the parallel transport.
7. Knows examples of the constant curvature surfaces and properties of geodesic triangles.
8. Understands gemeotric sense of the local Gauss-Bonnte theorem and topological sense of the global version.
9. Knows examples of the local abstract Riemannian manifolds in paricular hyperbolic plane.
Assessment criteria
Final grade based on an essay and written exam consisting of quiz and problems.
