Title "Spectral Properties of Group Algebra Elements"

Abstract:  We are principally interested on determinant calculation and 
on eigenvalues with multiplicities determination of the regular 
representation of group algebra element. We first briefly review the 
representation of group algebra and its connection with arrangements of 
hyperplanes. After that, we expose the determinant calculations of 
elements of the group algebra of the symmetric group and of the 
hyperoctahedral group. We also expose the eigenvalues with 
multiplicities determination of an element of the group algebra of the 
symmetric group. Then, we finish with the presentation of an open 
problem which is the eigenvalues with multiplicities determination of an 
element of the group algebra of the hyperoctahedral group.
