In the lecture course we will introduce the participants to the basic ideas and methods of differential topology. The idea of differential topology is to understand the interaction of smooth manifolds and their maps with the topology of manifolds using differentiable methods. For example, suitable invariants will be constructed which allow do distinguish manifolds up to diffeomorphism or to calculate topological information from differentiable data,

Examples in this direction are the mapping degree of smooths maps or the Poincaré-Hopf theorem which shows how the index of a vector field maybe used to calculate the Euler characteristic of a manifold.

The methods which we will encouter are important for the consideration of many problems in topology, geometry and global analysis.
