    Smile Prove adjugate-ness

    $\displaystyle A$ is self-adjugate [$\displaystyle A^*=(\overline{A})^T=A$] and $\displaystyle U$ unitary matrix.

    How to prove that $\displaystyle UAU^*$ is self-adjugate?

    EDIT: I'm almost certain that I got words right, but still slight chance of having terminology off.
