Pairs of matrices that have the same immanant

Research output: Contribution to journalArticlepeer-review


Let χ be an irreducible C-character on the symmetric group Sn and B = [bij] be an n × n matrix over C. The function dχ(B) = ∑σ∈Sn χ(σ) Πi=1n biσ(i) called an immanant. The main result of this paper is describing some matrices A satisfying dχ(AB) = dχ(B) for a given matrix B.
