Co-isometric operator%invariant subspace%factorization
This note discusses the co-isometric solutions of the operator equation CU +U*C ＝ 2D, establishes a correspondence between such solutions and the self-adjoint so-lutions of the algebraic Riccati equation X2 - iDX + iXD + D2 - C2 ＝ 0, and gives allpossible co-isometric solutions parametrically. Some mistakes of Dobovivsek's results arecorrected.
