The complete relationship between the kth anti-diagonals and the eigenvalues of an n×n (k≤n) real symmetric matrix is obtained. When k is even, the relationship is weak majorization. The Hermitian case is also studied. Similar results are obtained for real and complex skew symmetric matrices. © 2012 Elsevier Inc. All rights reserved.
