Young Row-Strict Quasisymmetric Schur Functions and 0-Hecke Modules
Abstract.
We give a representation-theoretic interpretation of the Young row-strict quasisymmetric Schur basis of quasisymmetric functions by constructing modules of the 0-Hecke algebra whose quasisymmetric characteristics are the Young row-strict quasisymmetric Schur functions. Additionally, we classify when these modules are indecomposable.
