The characteristic polynomial of some anti-tridiagonal 2-Hankel matrices of even order

João Lita da Silva

Abstract


In this paper we derive the characteristic polynomial for a family of anti-tridiagonal 2-Hankel matrices of even order at the expense of Chebyshev polynomials giving also a representation of its eigenvectors. An orthogonal diagonalization for these type of matrices having null northeast-to-southwest diagonal is still provided using prescribed eigenvalues.
