Basic algebra: vector spaces, groups, factor groups, homomorphisms.
Basic analysis in \R^n: continuous maps, convergence, differentiable maps.
The goal of the course is to provide an introduction to the basic notions of homology and cohomology theory, and show some simple (and some more sophisticated) applications of these techniques in topology. Ideas from homology are present in all modern directions of mathematics, and we will show some appearances of those as well. If time premits, at the end of the course we will see further applications of the concept of homology in knot theory.
