Learning outcomes: 
A student understands: :  Notions of an abstract smooth manifold, tangent vectors and their various interpretations. A differential of a smooth map. The role played by the algebra of smooth functions.  Variuos interpretations of vector fileds and their Lie bracket.  Constructions on vector bundles as generalization of linear algebra. Structures on vector bunldes (orientation, metric, symplectic etc.)  Why one integrates differential forms on manifolds. Geometric sense of the Stokes theorem.  Notion of covariant derivative and parallel transport as additional structures on manifolds.  How Riemannian metric defines a compatible connection. A students knows examples of:  abstract manifolds: projective spaces, abstract surfaces, construction of manifolds as orbit spaces of group actions. Lie groups.  manifolds of constant curvature; in particular hyperbolic geometry.  parallel transport and geodesics on some manifolds. A student is able to demonstrate geometric arguments on drawings and expose mathematical reasoning in written form.
