Introduction to algebraic K-theory
This is the website for the course I'm co-teaching with Kaif Hilman on algebraic K-theory in the summer semester of 2024 at the Max Planck Institute for Mathematics in Bonn.
Course: Introduction to algebraic K-theory
When: Wednesday 14.15 - 16.00 and Friday 10.15 - 12.00.
Where: MPIM Seminar Room
Lecture notes: Link
The overall goal of this course is to cover the fundamental theorems of algebraic K-theory in the modern formalism of ∞-categories. We provisionally aim to cover the following topics:
Preliminaries on ∞-categories
Group completion K-theory and the group completion theorem
Quillen's +-construction
Algebraic K-theory of stable ∞-categories
Waldhausen's additivity theorem
The localization theorem
The theorems of the heart
K-theory of pullbacks after Land--Tamme
Application: Purity in telescopically localized algebraic K-theory
