Abstract
The extended Schur functions form a basis of quasisymmetric functions that contains the Schur functions. We provide a representation-theoretic interpretation of this basis by constructing -Hecke modules whose quasisymmetric characteristics are the extended Schur functions. We further prove these modules are indecomposable.
