Immanant preserving and immanant converting maps
 
 
Description: 

Let Mn be the  algebra of all n-square complex matrices. I will characterize maps φ:MnMn that satisfy:

 

dχ(φ(A)+λφ(B)) = dχ'(A+λB)

 

for all A,B ∈ Mn and every complex number λ; where χ and χ' are arbitrary irreducible complex characters of Sn.
