Rationality problems

**Abstract:**A classical theme in algebraic geometry is to determine how far an algebraic variety is from projective space. Several notions have emerged in this context: rationality, stable rationality, unirationality, and rational connectedness. I will discuss new ideas and constructions that emerged in this area and that led to solutions of long-standing open problems.
