On Kostant's weight $q$-multiplicity formula for ${\mathfrak{sl}}_4(\mathbb{C})$

Rebecca E. Garcia, Pamela E. Harris, Marissa Loving +5

The $q$-analog of Kostant's weight multiplicity formula is an alternating sum over a finite group, known as the Weyl group, whose terms involve the $q$-analog of Kostant's partitio…
