I will give the Seminar’s second talk for Semester 1 tomorrow afternoon on Zoom. Please find the details below. Anyone who would like to attend the talk or join the mailing list is warmly invited to e-mail ciappara@maths.usyd.edu.au. Title: Derived categories and functors Abstract: I will begin by recalling some of what was said about triangulated categories last week, before introducing the main character of this week’s story: the derived category of an abelian category. To construct this category and understand its morphisms explicitly, we will discuss localisations of categories in general. The final part of the talk will concern derived functors, their main properties, and some key examples. Time and date: 2 pm, Wednesday 23 March Seminar website: https://www.maths.usyd.edu.au/u/ciappara/SAS.html
