摘  要: Measures of irrationality for hypersurfaces of large degree

A classical question in algebraic geometry is to determine whether ornot a variety is rational. In this talk, I will focus on its oppositeside: how "irrational" a variety can be? In particular, I will discuss my work on certain measures of irrationality of hypersurfaces of large degree in projective spaces.
