Chromatic (co)homology of finite general linear groups

Abstract

We study the Morava $E$-theory (at a prime $p$) of $BG{L}_d(F)$, where $F$ is a finite field with $|F|=1(\mathrm{mod}p)$. Taking all $d$ together, we obtain a structure with two products $\times$ and $\bullet$. We prove that it is a polynomial ring under $\times$, and that the module of $\times$-indecomposables inherits a $\bullet$-product, and we describe the structure of the resulting ring. In the process, we prove many auxiliary structural results.
