Course Syllabus

Abstract

Grothendieck duality is a deep generalization of the Serre duality in algebraic geometry, which holds for proper morphisms of schemes and complexes of quasi-coherent sheaves. The goal of this course is to give a complete modern proof of the Grothendieck duality following ideas of A. Neeman. The proof is based on the Brown’s representability theorem, which is a general theorem on compactly generated triangulated categories. The course will consists of two part. In the first part we’ll develop general theory of triangulated categories from the definition to the Brown’s representability theorem with applications to derived categories of abelian categories. This part can be considered as a second course in homological algebra based on the notion of triangulated categories. In the second part of the course we apply those techniques to the derived categories of the quasi-coherent sheaves on schemes. We’ll show that derived categories of the quasi-coherent sheaves on quasi-compact quasi-separated schemes are compactly generated, and that compact objects are the same as perfect complexes. Derive existence and general properties of the functor f^\times and its relations to the dualizing objects on schemes.
