Aims
The purpose of the course is to provide students with basic notions and classical results in algebraic and differential topology.
Content
Locally Euclidean spaces, topological manifolds, differential manifolds. Examples of differentiable manifolds. Tangent spaces. Equivalent definitions for the tangent space of a differentiable manifold. The tangent map. The tangent bundle of a differentiable manifold. Vector bundles; examples, operations. The partition of unity. Submanifolds. The rank theorem. The inverse function theorem. The Sard@s theorem. The Whitney@s theorem.
Manifolds with boundary. Submanifolds of the manifolds with boundary. The degree modulo two of a map.
Elements of Riemannian geometry. The existence of Riemann metrics on a manifold. Quotient topologies. Examples of quotient spaces. Attaching cells.
The groups π_n(X, x_0). The fundamental group. The homotopic invariance of the homotopy groups. The computation of the fundamental group for the n-dimensional sphere and for the n-dimensional torus. Brower@s fixed point theorm. The fundamental theorem of algebra. Groups of relative homotopy. The exact homotopy sequence of a topological pointed pair. Covering spaces. Applications of the covering spaces for the computations of certain homotopy groups.

Assessment
During the semester, th students will present individual homeworks, which provide 70% of the final grade. An oral exam contributes with the remaining 30%.
