Recent Trends in Quasisymmetric Functions
Sarah K. Mason
This article serves as an introduction to several recent developments in the study of quasisymmetric functions. The focus of this survey is on connections between quasisymmetric fu…

Quasisymmetric (k,l)-hook Schur functions
Sarah K Mason, Elizabeth Niese
We introduce a quasisymmetric generalization of Berele and Regev's hook Schur functions and prove that these new quasisymmetric hook Schur functions decompose the hook Schur functi…

Dual Immaculate Quasisymmetric Functions Expand Positively into Young Quasisymmetric Schur Functions
Edward E. Allen, Joshua Hallam, Sarah K. Mason
We describe a combinatorial formula for the coefficients when the dual immaculate quasisymmetric functions are decomposed into Young quasisymmetric Schur functions. We prove this u…
