Abstract. Toric varieties provide interesting examples due to their relation with combinatoric and algebraic geometry. In particular, in (co)degree 2, the Poincaré morphism can be interpreted in terms of divisors. Characteristic classes and intersection homology can also be computed explicitly, using the algebraic torus action on a toric variety. Examples of each situation will be given during the lecture.
