2) The course covers basic as well as more advanced aspects of the theory of Fourier--Mukai transforms for algebraic varieties and, more generally, of derived categories. In particular, we will cover the classification of algebraic varieties up to derived equivalence in the known cases (abelian varieties, K3 surfaces, Calabi--Yau varieties, Fano varieties, varieties of general type, etc). The course will present the central techniques (Hochschild cohomology, necessary and sufficient conditions for equivalences) and open questions. If time permits, we shall talk about t-structures, stability conditions (a la Bridgeland), the group of autoequivalences and might touch upon aspects related to mirror symmetry.

4) The focus of the course will be the problem of classifying irreducible components of the spaces of algebraic foliations of codimension one on complex projective spaces of dimension n>2. This problem was completely solved for foliations of degree zero, one and two, and it remains open for higher degrees. On the other hand, some irreducible components are known in general: components of pull-back type (linear and non-linear), some components consisting of foliations with rational first integral, components defined by logarithmic differential forms, and the so-called Exceptional components, parametrizing foliations containing n-1 foliations of dimension one. Along the course we will expose the known results and the techniques involved in their proof.
