Oscar Randal-Williams (University of Cambridge, UK): E∞-algebras and general linear groups
Abstract
I will discuss joint work with S. Galatius and A. Kupers in which we investigate the homology of general linear groups over a ring A by considering the collection of all their classifying spaces as a graded E∞-algebra. I will first explain diverse results that we obtained in this investigation, which can be understood without reference to E∞-algebras but which seem unrelated to each other: I will then explain how the point of view of cellular E∞-algebras unites them.
