The Drinfeld stratification for $${{\,\mathrm{GL}\,}}_n$$ GL n

Abstract We define a stratification of Deligne-Lusztig varieties and their parahoric analogues which we call the Drinfeld stratification. In the setting of inner forms of $${{\,\mathrm{GL}\,}}_n$$ GL n , we study the cohomology of these strata and give a complete description of the unique closed str...
