Seminar zum homofonischen Algebra

Masters Seminar in Homological Algebra

This is a seminar in the foundations of homological algebra, with applications to commutative algebra. We will introduce such basic notions as triangulated categories, Verdier localization and dervied functors, with examples furnished by the homotopy category of complexes and the derived category of an abelian category. We will look at the homological algebra of modules over a ring, discussing Tor and Ext and using these tools to derive results in commutative algebra, such as the homological characterization of regular local rings. For more details as to the topics and sources, please see the Seminar Program. For details as to the individual lectures, see the Lecture Program

The seminar meets Fridays, 14-16 Uhr in WSC-S-U-3.03
