In this lecture for one semester the basic facts are explained about smooth manifolds, vector fields and tensor fields, affine connections, torsion, curvature, parallelism and geodesics. Further, Riemannian metrics on manifolds and canonical connections belonging to Riemannian metrics, extremal properties of geodesics, sectional curvature.

Basic notions from general topology. Topological and differentiable manifolds, maps between manifolds. Submanifolds in the Euclidean space. Tangent spaces, tangent maps, vector fields, Lie bracket of vector fields.

Affine connection on a manifold as differentiation of vector fields. The Levi-Civita connection on a manifold in R^n. The parallel transport along curves, geodesic curves - definitions and existence theorems. Exponential map at a point. The torsion tensor field and the curvature tensor field, its geometric meaning.

Riemannian (pseudo-Riemannian) metric, the induced structure of a metric space. The Riemannian connection - existence and uniqueness, relationship with the Levi-Civita connection (on a submanifold with induced metric). The Gaussian formula and its geometric interpretation for surfaces - Gauss theorem. The Gauss curvature of a surface. The sectional curvature of a Riemannian manifold, spaces with constant curvature. Extremal properties of geodesics. Global properties of geodesics on a complete Riemannian manifold.

Possible extension: Divergence, gradient and Laplace operator on a Riemannian manifold.
