Alexander Kupers: Double Steinberg coinvariants and the homology of general linear groups

Abstract: I will explain what the computation of double Steinberg coinvariants, a variation on row reduction, tells us about general linear groups of infinite fields. This sheds new light on results of Nesterenko and Suslin, and provides insight into the homology of these general linear groups outside a stable range. This is joint work with Soren Galatius and Oscar Randal-Williams.
