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 &#960;_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.

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%.
