Chromatic (co)homology of finite general linear groups

Samuel M A Hutchinson, Samuel J Marsh and Neil P Strickland

Algebraic & Geometric Topology 22 (2022) 1511–1614
Abstract

We study the Morava E–theory (at a prime p) of BGL d(F), where F is a finite field with |F| = 1(modp). Taking all d together, we obtain a structure with two products × and . We prove that it is a polynomial ring under × and that the module of ×–indecomposables inherits a –product, and we describe the structure of the resulting ring. In the process, we prove many auxiliary structural results.
