Some Conjectures for Immanants

open access: yesCanadian Journal of Mathematics, 1992
AbstractWe present a series of conjectures for immanants, together with the supporting evidence we possess for them. The conjectures are loosely organized into three families. The first concerns inequalities involving the immanants of totally positive matrices (Le.,real matrices with nonnegative minors).

A2-web immanants [PDF]

open access: yesDiscrete Mathematics, 2010
We describe the rank 3 Temperley–Lieb–Martin algebras in terms of Kuperberg’s A2-webs. We define consistent labelings of webs and use them to describe the coefficients of decompositions into reduced webs. We introduce web immanants, inspired by Temperley–

Linear transformations that preserve immanants [PDF]

open access: yesLinear Algebra and Its Applications, 1994
We characterize the linear transformations on matrices that preserve the immanants, i.e., dχ(T(X))dχ(X) for all X, where χ is an irreducible character of degree greater than one on Sn.

Immanants of combinatorial matrices [PDF]

open access: yesJournal of Algebra, 1992
The arbitrary immanants of three matrices whose determinants are known to be generating functions for sets of combinatorial objects are examined. Combinatorial interpretations are given for the immanants of the Matrix-tree matrix, and a special case of ...

Hecke algebras and immanants [PDF]

open access: yesLinear Algebra and Its Applications, 1994
We describe how character values of certain Hecke algebras can be used to give linear combinations of immanants which are guaranteed to be positive on all Hermitian positive semidefinite matrices A.

Inequalities involving immanants [PDF]

open access: yesLinear Algebra and Its Applications, 1994
We summarize the recent progress toward determining the ordering of the normalized immanants regarded as generalized matrix functions and restricted to the n × n positive semidefinite Hermitian matrices.
