Masterclass Session 1: 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.
