摘要:We consider the centralizer algebra of a matrix in the full matrix algebra and show that this subalgebra of the matrix algebra has the property of Frobenius extensions. By applying elementary symmetric polynomials, we consider the isomorphism problem of invariant algebras, and give partial answers. The talk presents some joint works with J.B. Zhang.
