Abstract
In this paper, the conjugate secondary eigen values (con-s-eigen values) of a matrix, when properly defined, obey relations similar to the classical inequalities between the s-eigen values and s-singular values. Several interesting secondary spectral properties of conjugate secondary normal (con-s-normal) matrices are
indicated. This matrix class plays the same role in the theory of s-unitary congruence as the class of snormal matrices plays in the theory of s-unitary similarities.
