Flagged Weyl modules for two column shapes Original Research Article

This paper investigates representations of the Borel subgroup of the general linear group called flagged Weyl modules, associated to shapes in the plane having two columns. Two formulas for the characters of these modules are given, namely, a recurrence and a generating function over certain column-strict tableaux. Explicit Schubert filtrations (in the sense of Polo) are constructed for the duals of these modules.
