Super-immanants and Littlewood correspondences
Naihuan Jing, Yinlong Liu, Jian Zhang
In this paper, we introduce the notion of super-immanants for supermatrices over a supercommutative algebra. Using the super Schur-Weyl duality we show that the super immanants pla…

Immanant inequalities and weight spaces
Naihuan Jing, Yinlong Liu, Jian Zhang
We first obtain a trace formula for immanants of generalized principal submatrix of any complex matrix based on any weight space for finite dimensional representations of the gener…

Quantum Littlewood correspondences
Naihuan Jing, Yinlong Liu, Jian Zhang
In the 1940s Littlewood formulated three fundamental correspondences for the immanants and Schur symmetric functions on the general linear group, which establish deep connections b…
