Masterclass: Graph complexes and algebraic K-theory

Resumen: I will explain a certain space, K-theory of graphs, and explain how it relates to two other interesting mathematical objects: algebraic K-theory of the integers, and Kontsevich's graph complexes. Hopf algebra structures will play an important role, and I will discuss some consequences for group homology of general linear groups of the integers. Based on joint work with Brown, Chan, and Payne.
