Abstract: I will discuss two different ways to measure the complexity of singularities of a (globally-defined) complex hypersurface. The first is derived via (Hodge-theoretic) characteristic classes of singular complex algebraic varieties, while the second is provided by the multiplier ideals and jumping coefficients. I will also point out a natural connection between these two points of view. (Joint work with Morihiko Saito and Joerg Schuermann.)
