Higher direct images of dualizing sheaves


Abstract: I will talk about Koll\'ar's article bearing the same title in which he proves that higher direct images of dualizing sheaves have many properties in common with dualizing sheaves. The prototypical example of this phenomenon is that they satisfy a Kodaira type vanishing theorem. After an overview of the technical results of his paper (this is the interesting part of it) I will present the proof of a simplified version.
