Abstract: Let $ G$ be a finite group of Lie type (e.g. $ GL_n(\mathbb{F}_q)$) and $ U$ a maximal unipotent subgroup of $ G$. If $ \psi$ is a linear character of $ U$, then the unipotent Hecke algebra is $ \mathcal{H}_\psi=\mathrm{End}_{\mathbb{C}G} (\mathrm{Ind}_U^G(\psi))$. Unipotent Hecke algebras have a natural basis coming from double cosets of $ U$ in $ G$. This paper describes relations for reducing products of basis elements, and gives a detailed description of the implications in the case $ G=GL_n(\mathbb{F}_q)$.
