Equality of Dual Immaculate Functions Under Automorphisms
Maria Esipova, Stephanie van Willigenburg
The dual immaculate functions are an example of a Schur-like basis in the algebra of quasisymmetric functions. We classify when the image of a dual immaculate function under one of…

Symmetric quasisymmetric Schur-like functions
Maria Esipova, Jinting Liang, Stephanie van Willigenburg
In this paper we classify when (row-strict) dual immaculate functions and (row-strict) extended Schur functions, as well as their skew generalizations, are symmetric. We also class…

Chromatic quasisymmetric functions of the path graph
Farid Aliniaeifard, Shamil Asgarli, Maria Esipova +3
We show that the chromatic quasisymmetric function (CQF) of a labeled path graph on vertices is not symmetric unless the labeling is the natural labeling or its…
