Let a nonsingular S ∈ Mn (C) be given. For a nonsingular A ∈ Mn (C), set ψS (A) = S−1A−1S. We say that an A is ψS orthogonal if ψS (A) = A−1 and we say that A is ψS symmetric if ψS (A) = A. For a possibly singular B ∈ Mn (C), we say that B is ψS orthogonal if S−1BS = B; we say that B has a ψS polar...
